Sensors and Animals

I still remember my early days in the Navy, when accelerometers were relatively large and most definitely expensive. They also weren’t all that reliable at times. (An accelerometer measures the amount of acceleration in a specific direction.) However, they were necessary equipment components because they helped ensure that any measurements compensated for the ship’s yaw, pitch, and roll. In fact, accelerometers continue to have a high visibility role in performing this task as part of Inertial Measurement Units (IMUs) used in all sorts of equipment. Fortunately, modern accelerometers are extremely reliable, quite small, and cheap.

You probably have several accelerometers on your person. For example, they’re used to change the orientation of the picture produced by your smartphone. In fact, accelerometers are one of the most common sensors in use today because they provide much needed information about the manner in which the environment is changing for a particular technology. There are all sorts of ways in which you could use accelerometers to determine how an object is interacting with the real world.

Using accelerometers with animals has gone on for a long time now. In fact, they’re used so often that there is an actual name for the practice, animal biotelemetry. Most uses for animal biotelemetry affect wild animals in some way, but you can find uses for domesticated animals as well. I recently read about a new use for accelerometers in working with animals, Moove it! Tracking the common cow. The title would have you believe the accelerometers are used to monitor cow movement, which is partly true, but the purpose is to determine when the best time is to breed the cow so that she produces offspring at the most efficient time for everyone (including herself). I really enjoy learning about animals and conducting research to find ways to help them better when it comes to illness etc. I should probably start looking for animal research jobs in the UK since that would be my dream career! I guess it’s something for me to consider in the future.

The article points out that sensors are often used in ways that weren’t envisioned by their creator. In this case, the accelerometer is actually used for monitoring, rather than measuring direction. I look for continued new uses for sensors to come to light. These uses will help us overcome many of the issues that people face today in interacting with their environment. Let me know your thoughts about how accelerometers and other sensors might be used to track, monitor, and otherwise help both people and animals to lead better lives at [email protected].

 

Hugging Your Animals

Hugs are the universal communication medium for most animals. It may surprise you to discover that I hug all my animals on a regular basis. The reasons for hugging my animals are many, but from the animal’s perspective, it’s a matter of knowing that I’m OK—that I’m not going to hurt them. To keep an animal tame and workable, you need to respect its need for contact with you. Often, people have problems working with their animals because the needed relationship simply isn’t there. Here’s a picture of me hugging one of my chickens, Daisy.

The chickens are actually quite interesting because they curtsey to attract attention and tell me that they want to be picked up. The curtsey is kind of a half bow where they spread their wings slightly as if lifting out a dress. The point is that the hens really do want (and need their hugs).

The rabbits also need hugs and have a different way of demonstrating the need. One of my rabbits, Twilight, will sit on her hind legs and raise her front legs in greeting when I open the cage in the morning. If I don’t pick her up and pet her, she stomps her back feet when I leave to show that she’s really quite unhappy. It doesn’t have to be a long hug, just as long as I tell her that she’s special in her own way.

My two dogs, Reese and Shelby, want their hugs first thing in the morning, when I let them in from going outside. Each dog has her own way of getting petted. Shelby is quite dignified about the whole thing and sits patiently waiting until I pet her. A little nuzzle often tells me that her patience is running out. Reese is quite crazy and runs about in circles until I invite her over for a hug. Of course, it’s not enough to simply pet her back, she wants her belly petted as well.

Every morning Sugar Plum wakes me up by meowing at me and patting my face. If that doesn’t work, she gets Smucker involved (he stomps all over me). Failing that, the two cats get the dogs stirred up. All that howling, baying, and barking is impossible to ignore. Obviously, Sugar Plum wants to be paid for her efforts, and her hug is a required part of the payment. Smucker usually comes in after breakfast, sits on my shoulder for a while, and then sort of slides down into my lap for his hug.

Of course, the hugs don’t just help the animals. Hugs come with serious health benefits for humans too. I’ve noted that my mood improves after my hugs each day. The results are measurable too. Taking my blood pressure before and after a hug shows that it goes down every time. Lower blood pressure and heart rate will help me stay healthy and all it takes is a simple hug.

Some people might question whether my animals really do require hugs, or whether I’m anthropomorphizing natural behaviors that mean something else. At one time, I might have thought that animals really didn’t need the hugs—that their behaviors really did mean something quite different, but time has taught me that they need love too and a hug is one of the best ways to give it to them.

Dealing with a Rainy Summer

It has been a rainy summer so far in Wisconsin. Thank goodness it hasn’t been the kind that sees lots of flooding, as we had in 2008 when the entire town flooded out and I was locked in the house for days at a time. No, this has been a lighter, steady sort of rainy summer. It has rained often enough that the young lad mowing my lawn has had to work hard just to find days to do it and sometimes needs to come back another day because it starts raining right in the middle of cutting the grass. However, the things that tell you most that this has been a really rainy summer are the mushrooms and the mosquitoes.

The mushrooms are interesting because they’re growing all over the place and are of such diversity that they’re simply fun to look at. I’ll often wander around in the early morning hours looking at mushrooms before the dogs get out there and rip them up (yes, Reese and Shelby can get quite frisky during their morning game of Frisbee). If I knew a bit more about mushrooms, this would be a year to stock the freezer. As it is, I’m only positive enough about button, morel, and puffball mushrooms to pick them for eating (and even then I’m extremely careful).

The mosquitoes are a bit more of a problem. There have been notices on the radio that many of them carry West Nile Virus, a disease I’d prefer not to get. So, I’ve stocked up on the usual remedies and make sure I spray myself before I go out to work in the flower beds or gardens. A friend of mine did tell me that he’d recently contacted his local lawn care company (https://www.lawncare.net/service-areas/texas/) to come and spray a repellent on his lawn, meaning that his garden should now be free from mosquitoes. It also lowers his chances of catching that disease in his garden. Perhaps I’ll see if my usual remedies work in the garden, and then I can just contact a professional to remove the mosquitoes from my garden if they don’t work. Just to be prepared though, I’ve also been reading articles such as, “10 Signs You May Have West Nile Virus” so that I know what to look for.

The rains have had some interesting effects (other than the mushrooms) in my salad garden. The cherry tomatoes are already to the top of their cages and they’re producing blooms like crazy. At some point I’m going to be eating cherry tomatoes a bit more often than I might like. My plan is to collect enough up that I can dry them for later use. Dehydration is always a good way to preserve food for later use. Likewise, my green peppers are getting quite large. In fact, I picked my first green pepper (a tad small) the other day. The extra rain hasn’t seemed to affect the taste or quality of the peppers so far.

What I do worry about is my herbs. So far they’re growing like crazy, but I’m concerned that they won’t dry well and that they’ll lack some of the oils that they normally do. I tried some lime mint in tea the other day and it seemed a bit weak. The rest of the summer will determine just how the herbs do. I know they’ll definitely be usable, but it may require more of them to get the same effects as normal. Fortunately, none of the herbs seems to be rotting or having other problems so far.

Did I mention that the weeds absolutely love the rain too? It seems as if I can’t pick them fast enough and the nearly constant rain causes them to grow quite large, quite fast. Fortunately, I’ve been able to keep up well with everything except my personal garden, which is a little weedier than I’d like at the moment.

Dealing with Thin Shells

A while back I provided a post entitled Feeding for Healthy Chickens that described conditions where chickens could eat their own eggs. This post provides you with some good ideas on just what to do to prevent the problem in most cases. However, it seems that the post doesn’t go quite far enough. There are situations where the weather is cool, the chickens are perfectly healthy, and they aren’t eating their eggs when you’ll still see broken eggs in the coop. In this case, you see the whole egg and need to clean it up immediately. However, the defining characteristic of this condition is that the shell will be paper thin.

Chickens need sunlight, just like everyone else, to produce Vitamin D. In addition, chickens need quite a bit of calcium in their diet and it isn’t always easy to get them to eat enough. When you see that the chickens are healthy and that the weather isn’t too hot, but the shells are still thin, it’s a sign that the chickens likely have a Vitamin D or calcium deficiency. In this case, the thin shells came right after winter, so the problem was Vitamin D.

In order to combat this problem, you may need to resort to unusual measures. In order to fix this particular problem, I started feeding the chickens expired yogurt. No, the yogurt hadn’t gone bad yet, but it was far enough past the expiration date that it had started separating quite badly. The chickens won’t care. It turns out that chickens absolutely love yogurt and can’t get enough of it. Just make sure the yogurt you feed them is made with Vitamin D enriched milk or has the vitamin added to it.

After some experimentation, I found that I could get the shells to harden up by feeding our ten chickens 1 cup of yogurt each day for about a week. Given that I have a cheap source for expired yogurt, I’ll keep feeding them yogurt on a regular basis, but not continuously. Part of the problem here is to ensure you get high quality eggs without cutting your profits too much. An egg shell should be relatively thick and smooth. When you start to see the egg shell getting thin and rough, it’s time for more yogurt.

There is a problem that can occur when you feed the chickens too much calcium. I’ve actually managed to get the shells thicker than they should be and that makes the eggs hard to use. If you like your eggs over easy or sunny side up, it’s important to maintain the correct egg shell thickness. Let me know about your egg production problems at [email protected].

 

Appreciating the Healing Powers of Animals

I’ve always appreciated the ability of animals to make bad feelings better. There always seems to be something interesting going on with animals that makes the day more pleasant and happy. Of course, there is an almost continuous array of bird song in our area during the daylight hours. Just the happy song of birds is enough to make me smile.

When the native birds add antics to the mix, I sometimes get a good laugh in as well. Such is the case with a little downy woodpecker that visits the feeder near our house. He never seems to arrive right side up. No, despite his best efforts, he always seems to hit the perch upside down and must fight his way to an upright position. The vibrant mix of colors doesn’t help the woodpecker’s cause—he looks a bit like a clown anyway. Our particular downy woodpecker seems to have a bit more head color than pictures I see online show, but far less than a red headed woodpecker.

Now, when you mix native birds with chickens, you really get a visual treat. In most cases, the chickens try their best to ignore the native birds because they’re obviously better (at least, as far as the chickens are concerned). However, the other day the chickens didn’t have much choice in the matter because some sparrows decided to have fun with them. Imagine this scene for a moment, chickens running madly about flapping their wings and clucking crazily while sparrows are dive bombing them. I laughed so hard that it took several minutes for me to compose myself enough to come to the chicken’s aid.

In a contrast to the antics of the chickens, our rabbits are lovers, not fighters. They often need a hug. At the top of the hugging list is Twilight. She always wants a hug whenever I open her cage to feed her. In fact, she actively pursues hugs every time I walk by. She does this odd sort of clapping motion to attract my attention by sitting on her hind feet and moving her front paws back and forth.

Entertainment isn’t something that happens just outside either. Our dog Reese is hysterical. For one thing, she can’t go anywhere in a straight line. She runs in circles every time she goes from one place to another. When she’s excited, she mixes the frantic circles with a mix of barking and baying. How any one dog can look so happy and absurd at the same time is amazing.

Whenever Shelby (our other dog) senses that I’m blue, she offers me a paw. She’s not really looking for a handshake. Instead, she wants me to hold the paw—possibly for as long as I need to do so. So, I hold her paw and she washes my hand. It’s therapeutic, even if it does get a bit wet.

Another washer is Smucker who offers kisses by the gross. He likes to lean into my side and then wash my arms, hands, or other exposed body parts. Of course, the bath comes complete with purring.

Finally, Sugar Plum is absolutely frantic about getting petted. She’ll keep nuzzling me until I pet her (and keep petting her until she’s satisfied that I’ve petted her enough). Her purr is a bit louder than Smucker’s purr (as is her meow).

All of these behaviors (and many others) serve to help keep my calm and feeling good. I can actually measure a change in both blood pressure and heart rate after interacting with the animals. Many medical studies have noted similar results with other people, so I’m definitely not alone. The point is that animals provide benefits far beyond companionship and laughter. They also make it easier for people to deal with a host of problems in their lives. Let me know about your health benefit experience with a pet at [email protected].

 

Chickens at Play

A lot of people see chickens as being confined to a particular area and quietly pecking at the dirt for most of their lives. Meat chickens do have a certain lack of personality and do spend most of their time eating. However, laying hens are a completely different story. Depending on the breeds you get, you can see a wide range of interesting behaviors, some of which are quite funny.

There are still some snow hills in our yard. The other day I was looking out our kitchen window at one of them and there was a chicken at the top pecking into the top of the hill. She was obviously eating some of the ice in order to get a drink. However, it wasn’t long and another hen ran up the hill and knocked the first hen off. Now she was going after the ice. Soon, there was a general melee as different chickens proclaimed herself the queen of the hill. I was laughing so hard that I nearly dropped some dishes I was putting away. The hens looked so intent about their play and so funny at the same time.

A few days later I was out pruning our pear trees. Suddenly, one of the chickens (Daisy, an Americana) started clucking quite loudly—the sort of cluck that says, “Hey, I’ve done something really cool!” She jumped over the top of the run fence and waddled as quickly as she could to me, clucking intensely all the way. Then she curtsied. So, I petted her and told her was a good chicken she is, but the action didn’t satisfy. As I tried to go back to work she shrieked at me and curtsied again. So, I picked her up and took her back to the coop. She had laid a beautiful blue egg for me and wanted me to know just how beautiful it was. So, I accepted the egg and made a big deal over just how good a chicken she is, which seemed to satisfy her this time. Just why this particular egg was so special is beyond me.

Later in the same day, Violet, our Black Australorp, was making one of her usual speeches. She’s the queen of the coop and when she speaks, the other chickens listen. Just was she was saying on this particular occasion is beyond me. However, she was in fine form and rattled off quite a long discourse on something only other hens would care about. The other hens gathered around her and listened intently, murmuring to themselves in agreement with whatever it was that she was discussing.

There is seldom a day when our chickens don’t do something interesting and special. Even if they didn’t produce copious eggs, I’d keep them around just for the laughs they provide. I actually consider them an essential part of my health plan now. A laugh a day keeps the doctor at bay. If you do get laying hens, make sure you take time to enjoy their behaviors—you’ll be glad you did! Let me know about your interesting chicken stories at [email protected].

 

Odd Nature of Chicken Eyes

When it comes to thinking about how input is perceived, few people think about chickens. However, the whole range of perception has attracted my attention because I see the topics as being interrelated in various ways. I find it interesting that chickens actually have a kind of vision that most of us can’t really imagine. For one thing, instead of the orderly array of cones that humans have, chickens have a disorderly set of cones that actually rely on a different state of matter from those in human eyes. Chickens see color better than humans do and they see a wider range of colors. Humans see red, green, and blue. Chickens see red, green, and blue as well, but they can also see ultraviolet and have a special motion detecting cone (for a total of five cone types to our three).

There are a number of reasons I’m interested in the topic. Of course, we raise chickens and the more I know about them, the better. My interest goes way beyond just raising the chickens though. When I wrote Accessibility for Everybody: Understanding the Section 508 Accessibility Requirements, I experimented with all sorts of techniques for improving a human’s ability to interact with the world. A lot of people might think the book is focused on special needs, but really, it’s focused on accessibility of all sorts for everyone. When a hunter uses a scope to see a long distance in order to hit a mark, it’s a form of interaction that could easily fall into the accessibility category. The hunter is compensating for the lack of long range vision by using a scope (an accessibility aid of sorts). The scientific examination of chicken eyes could lead to discoveries that will help us create accessibility aids that will allow humans to see a vast array of new colors naturally, rather than through color translation (where a color we can’t see is translated into a color we can see), as is done now.

The potential for such study goes even further. Most people don’t realize that men are naturally less able to see color than women. For example, 8 percent of men are colorblind, but only 1/2 of one percent of women have the same problem and usually to a lesser degree. Even odder, some women possess a fourth cone so they can see a vast array of colors that most people can’t even imagine. Only women have this ability. However, it might be possible to provide men with the same color perception through the use of an accessibility aid—one possibly modeled on the research done on chicken eyes.

The ways in which this research could help us out are nearly endless. For example, we rely on the superior smell capabilities of trained dogs to sniff out bombs and drugs. Chickens, as it turns out, can be trained as well (not to the degree that dogs are trainable, unfortunately). It might be possible to train chickens to alert to color discrepancies that only they can see. We could use trained chickens in the same way we currently use dogs.

There are other ways in which this research could benefit us. The actual chemistry of a chicken’s eye is unique. Studying the chemistry and discovering how it works could yield new compounds for us to use.

We look at various animals and think they’re only useful in one way. However, the more time I spend interacting with our animals, the more I come to realize that they really are useful in a host of ways. The next time you look at a laying hen, consider the fact that she can see things you’ll never even imagine. Let me know your thoughts about chickens, the unique nature of chicken eyes, and accessibility at [email protected].

 

Winter Egg Production

Chickens are affected by the amount of daylight available. In fact, layers typically need 12 to 14 hours of light each day to lay eggs consistently. Commercial egg laying operations will provide this amount of light artificially, if necessary, to ensure the chickens keep laying eggs. Of course, commercial egg laying operations also heat their coops and keep chickens in conditions that reduce the quality of the egg that you get in the store. Part of the benefit of raising chickens in natural conditions is that you obtain a high quality egg that actually contains more good elements and fewer bad elements (such as cholesterol and fat). However, there is a cost involved with getting this higher quality egg and that’s a reduced winter production.

A number of sources online mistakenly say that egg production stops completely during the winter months. However, my own experience says otherwise. Yes, the production is greatly reduced, but we still obtained 63 eggs from our ten hens during the month of December. This is contrasted with 248 during August, which is a typical summer month. So, you probably won’t have enough eggs to sell in December if you bake and eat eggs regularly. However, you also won’t have to go completely without eggs.

Of course, the question is why you wouldn’t provide a light in the coop if it will induce the chickens to lay more eggs. The problem with using a light is that it robs the chickens of important nutrients they need during the winter months. The chickens need these nutrients to stay warm during the winter, especially if your coop is unheated. Heating and lighting a coop is also expensive, so you’d need to consider the tradeoff in additional costs. When all is said and done, most small operations will be better off letting the chickens have a bit of a rest during the winter.

You can improve egg production by ensuring your coop has south facing windows so that the chickens do get the maximum light available. This strategy will also keep the chickens warmer because the sunlight will heat the coop during the day. Given the experience we’re having with the chickens, I credit the south facing window for getting any eggs at all.

One of the things you can do if you really must have more eggs during the winter months is to freeze your eggs. That’s right, you can freeze eggs during the late fall (as production is going down) for use during the winter months. You can whip the eggs up and freeze them for up to 12 months.  It’s also possible to freeze just the whites.  Unfortunately yolks don’t freeze well, so you need to choose how you plan to use your eggs as part of your strategy.

There are tradeoffs for nearly any self-sufficiency strategy you use. We’ve chosen to follow a natural path when it comes to egg production by giving our chickens a bit of a vacation during the winter months to ensure that we continue to get quality eggs when they do lay and also to extend the life of our layers by not overtaxing their systems. What is your experience with winter egg laying? Let me know at [email protected].

 

Cleaning the Coop in December

It’s December and time to check on your outside animals to ensure they remain comfortable. The rabbits are relatively easy. All you really need to do is ensure the cages are remaining reasonably clean (wire brush those bunny pellets from the cage’s hardware cloth) and that any protective measures, such as the window plastic you put in place to keep the wind at bay, are still in place and in good condition. The entire process will likely take less than an hour (if that long—my six cages took about 15 minutes).

The chickens are another story. You need to check the weather carefully and try to find a day when the temperature will get above freezing, if possible. The manure in the coop will be a lot easier to get up if you can get it to defrost a little. You want to clean out all of the old hay and manure. Unlike your fall cleanup, you won’t wash the nest boxes. In fact, this is a really bad time to do anything with water in the coop (except for the chicken’s drinking water) because it won’t dry properly. The idea is to clean as much as possible by scraping up the manure and getting it out of the coop onto your compost heap. I find that a combination of a barn shovel and a wide bladed putty knife do the job quite well.

This is also the time to check for air leaks again. Your chickens can keep cozy if your coop is relatively air tight.  You don’t want to close it up so tight that the ammonia fumes build up and hurt the chickens, but you also don’t want anything like a strong breeze in the coop.  The chickens will normally keep warm by huddling together at night on top of their nest box or other roosting area you provide. So, it’s essential that you keep the air leaks under control.

When replacing the hay, make sure you pack each nest box a little more than you would in summer to give each chicken a nice place to lay her egg. I’ll use regular alfalfa hay during the summer months because it’s stiffer and breaths better. However, during the winter months I use grass hay. It’s softer and provides better warmth. You must make sure the hay you use is completely dry and mildew free because it absolutely won’t dry during the winter months and you don’t want your chickens to acquire respiratory diseases.

Because it is winter, the chickens are more likely to keep you entertained as you clean the coop. Remember that the coop is their home, so you need to be patient as you work with them. During the cleaning process, one chicken proceeded to scold me, but another pecked at my feet (apparently trying to get off all the snow). A third kept insisting that she needed to be held and petted (slowing my progress). All this attention is quite normal during the winter cleanup.

Keeping the coop clean is quite important if you want to maintain your chicken’s health. That means getting out in winter, when conditions for cleaning are less than ideal. Working on the one or two days during the winter when the temperatures get a little higher will make things a lot easier, but even so, you’ll be trying to clean the coop with a bulky jacket and gloves on, so it’s going to take more time than in the summer months.

Preparing Eggs for Sale

It may not seem like a particularly important topic at first, but if you plan to sell some of your eggs, you must prepare them for sale properly. Otherwise, you’ll quickly lose your customer base. No one will say anything to you about the reasons for not buying your eggs—they simply won’t buy them. After a while, you’ll be left with a lot of eggs on your hands and no buyers.

When you get the eggs from the coop, make sure you wash them. This might seem like an obvious thing to do, but some people have actually tried to sell unwashed eggs, which is hazardous to a customer’s health, as well as unappealing. I normally use Dawn Antibacterial soap to wash the eggs and then rinse them thoroughly. The soap ensures that the outside of the egg is free of pathogens. Of course, you need to perform this process carefully or else you’ll end up with a lot of unsellable eggs.

After you allow the eggs to air dry (or dry them carefully with a towel), you need to inspect them carefully. Any flawed eggs go into my personal pack. Eggs with cracks are cooked thoroughly and fed either to the dogs or cats. There isn’t a good reason to waste good protein, but if the egg has any cracks at all, you can’t vouch for the integrity of the content. A mix of egg, rice, and leftover meat makes for a dandy addition to your pet’s daily food. Sometimes I throw in a few leftover vegetables as well.

We don’t have any roosters. If we did, we’d also need to candle the eggs to ensure there were no embryos inside. Because we buy our chicks from other places, we won’t ever have roosters for our laying hens. You need to decide on whether to keep roosters based on your particular egg laying needs. However, it’s still possible that our eggs could have a blood spot in them. We simply offer our customers a replacement egg should this happen. So far, it never has, but it could happen given that our chickens are free range. Theoretically, you can candle the eggs to find this sort of problem, but it’s still possible to miss it, so having a replacement policy is the best way to go.

At this point, you have a number of washed eggs that lack flaws. It’s time to weigh them using an egg scale. I generally keep small eggs for my personal use. Medium-sized eggs are sold at a discount, traded for something I need, or given to friends and neighbors. The large and jumbo eggs are placed into cartons and sold at full price.

Create an attractive display for your eggs. For example, I’ve set up kid friendly egg cartons. The cartons will contain an attractive mix of blue, green, brown, tan, and speckled eggs (the range of colors the hens lay). Placing the eggs in some sort of pattern also helps. Even though the inside of the egg is the same in all cases, the eye catching patterns really help to sell your eggs to the public. Of course, adults may prefer a less colorful display, which means grading the eggs by color and placing like colors in a carton. The point is to make your eggs look especially nice.

Preparing your eggs properly will help keep you in sales. In fact, a combination of high quality and classy presentation will usually net you more customers than you can accommodate as long as your prices are also in line with what the market will allow.
