Roosters really do know what time it is

My rooster Artemis announcing the start of day 

Normally, at 4am like clock-work, I'm awakened by Artemis announcing the start of another day. In summer it can be as early as 3am! This sets off ALL Solly's roosters and I can assure you, NOTHING can sleep through that racket! Their crowing has now set MY internal clock and I'm normally awake just before the crowing starts.

The rooster's morning cock-a-doodle-doo is driven by an internal clock, finds new research, suggesting that male chickens really know the time of day.

The study, detailed in the journal Current Biology, found that roosters put under constant light conditions will still crow at the crack of dawn.

Past studies have found that a myriad of animal behaviors are driven by an internal clock: at night, a dip in insulin causes humans to process food more slowly, and even blind cave fish use a circadian clock to tell time.

"Cock-a-doodle-doo' symbolizes the break of dawn in many countries," said study author Takashi Yoshimura of Nagoya University, in a statement. "But it wasn't clear whether crowing is under the control of a biological clock or is simply a response to external stimuli."

Because stimuli throughout the day — such as car headlights — will set off a rooster's crow at any time, it was also possible that increasing light was the trigger for the cock's crows.

To find out Yoshimura and his colleagues put 40 roosters in a setting with constant light, then recorded when they crowed.

Sure enough, the chickens crowed at daybreak regardless of the light conditions. The roosters also crowed at other times of day and in response to light and the crows of their fellow chickens, but those behaviours were much stronger at daybreak. The findings suggest that an internal circadian clock, rather than external conditions, drive the behaviour.

A bath and a clean nest

After Kiep's broodiness finished a couple of days ago, I decided she needed a bath after sitting on her golfball for almost a month. She looked decidedly drab and worse for the wear and needed a bit of special TLC. (I take all the eggs away from my girls, I do not want any more chickens and they all seem to be quite happy with the golf ball scanario!)

I prepared some luke warm water in a tub and put her in. At first she struggled a bit (it was her first bath ever), but the minute she felt the warmth of the water, she actually lay down! I gently shampooed her back, chest and vent area, careful not to ruffle her feathers too much. 

I remembered using vinegar as a youngster to rinse my hair after a wash when we'd run out of conditioner and it always left my hair soft and shiny. So, after a first rinse, I transferred Kiep to another tub with a bit of vinegar in the water, gave her a good rinsing, dried her gently with a towel and then used the hair dryer to get her nice and dry. I was a bit worried about the noise of the hair dryer, but she seemed to enjoy it, fluffing up her feathers to let in the hot air.

After she was all nice and dry, and oh so extremely soft and fluffy! we went out into the bathroom court-yard, where she spent a while preening and getting her feathers in the correct order again and when she was ready, I led her out to the main garden where she immediately rushed up to Artemis, greeting him with some wing-flapping and a lot of prancing around.

Now it was time to also clean out her nest-box, which is on top of one of my art tables in my studio. I cleaned out the box thoroughly, put in fresh grass and then placed it back, all nice and clean. 

Later in the morning she strutted into my studio to deliver her breakfast, but it turned into a big to-do. She took one look at the nest and, horrified, she proceeded to unpack all the grass and then putting it back to her liking before settling down to the serious job of laying the egg! 

 Her eggs are different after this last broody incident, much bigger and not so white, more brown. My little girl is growing up now…

Snooky and Avian Botulism

One evening about two weeks ago, when I was closing my girls up for the night, I noticed that one of my hens, Snooky, didn't look well at all. She entered the coop with her wings slightly spread and her tail hanging very low and my first thought was, "Oh no! A stuck egg!" I inspected her, but couldn't feel an egg at all. The next morning, when I opened up for the chickens, I found her in one of the nest boxes, unable to walk. I brought her inside and did a gentle internal examination, using some petroleum jelly on my finger, to feel if the egg was there now, but still nothing. And she was displaying some other disturbing symptoms. She couldn't use her legs at all, they seemed totally paralysed and she also had trouble sitting up straight and kept on falling over, either sideways or backwards. I did a thorough check for any other injuries but found nothing. The funny thing was that she didn't seem sick at all. She was alert and her eyes were bright, her comb was bright red and she ate and drank readily without any coaxing, but I had to hold her up so that she could reach the food and water. Her droppings were also perfectly normal.

Totally perplexed, I put her in a basket next to me in my studio and I had to wedge her in the corner otherwise she kept on falling over. As it was the weekend and a vet not readily available, I started treatment with a general antibiotic (Baytril) which I keep on hand for emergencies, just in case it was an infection of some sorts.

My mind was racing, trying to figure out what it could be. I searched all over the internet for 'paralysed chicken' and 'chicken can't walk' and after a long search I discovered Avian botulism which described all the symptoms I found with Snooky. I was horrified as it stated that there was no cure and that affected livestock had to be culled. 

Avian botulism is a paralytic disease caused by ingestion of a toxin produced by the bacterium Clostridium botulinum - an anaerobic, Gram positive, spore-forming rod. It acts by blocking nerve function and leads to respiratory and musculoskeletal paralysis.  In all cases, illness is caused by the toxin made by C. botulinum, not by the bacterium itself. There are several types of toxin produced by strains of this bacteria with birds being most commonly affected by type C and to a lesser extent type E.

This bacteria is widespread in soil and requires warm temperatures, a protein source and an anaerobic (no oxygen) environment in order to become active and produce toxin. Decomposing vegetation and invertebrates (i.e., insects) combined with warm temperatures can provide ideal conditions for the botulism bacteria to activate and produce toxin.

Birds either ingest the toxin directly or may eat invertebrates (e.g. chironomids, fly larvae) containing the toxin. Invertebrates are not affected by the toxin and store it in their body. 

It struck me that, just two days prior, I had composted my whole garden, never giving a thought that it might harm the chickens. I then Googled 'chickens and compost', and found a widespread consensus that compost is NOT harmful to chickens and that many farms have compost heaps and that the chickens just love scratching around in it. So now I was really puzzled.

Come Monday, I was off to the vet with Snooky and here's where it gets a bit dicey. Not many veterinarians are knowledgeable about chickens or birds in general and the vet's puzzlement was even greater than mine. I mentioned to her that I suspected Avian Botulism and her vague answer, after consulting with her senior partner, was that it was quite probable that it was Botulism as the botulism bacteria is the only bacteria or virus that produces a (neuro) toxin that causes paralysis. After giving her a vitamin shot and another shot of Baytril, they concurred that I should keep up my treatment of Baytril for a couple of days but that they are positive that it would be better to have her euthanised.

I took Snooky home in despair and kept up the treatment for another two days. It was now almost a week and she showed no signs of improvement. I was on the point of going back to the vet to have her put down when I decided to give her some physio. I know that sounds silly, but I really was desperate. I massaged her back and her legs (the drumsticks) a couple of times a day and also gently pulled her legs in and out, exercising them a bit. I also took her outside to the other chickens in the chicken run three or four times a day, putting her on the lawn where she would just fall over, having to support herself with her wings or rest on her elbows. I also supported her with my hand under her tummy, pushing her forward gently so that her legs "walked", keeping this up for a couple of minutes before taking her inside to rest.

On the third day of her "exercise regime", I took her out to the garden where all the other chickens were enjoying their sand baths and put her in some loose sand. She was totally ecstatic, trying to go through the motions of kicking up sand, but all she could manage was to flick some sand on her back with her beak. But within a couple of minutes she was managing to sit up straight without falling over! After about ten minutes we went back inside and I rewarded her with some of her favourite snacks. The rest of the day she was sitting up straight in her basket without any support, even managing to preen some of the sand out of her feathers and reaching into the food bowl on her own. In the meantime, I carried on with the physio, regularly massaging her back and legs.

The next day (fourth day) when I took her out to the garden and put her down in the sand, she struggled up onto her legs and actually stood! I was cheering her on and after a minute or two she took her first tentative step and proceeded on a very wobbly walk through the garden. *I was totally ecstatic!*

It soon became apparent to me where she was going - she had seen a lovely spot where Chi-Chi was sand bathing and without further ado she exercised her right in the pecking order by getting Chi-Chi to give up this prime spot, where she immediately got right down to the business of sand bathing, kicking legs and flapping wings and getting a good covering of the good stuff!

After that, there was no stopping her and she started exploring the garden, every now and then stumbling over a rock and falling down, but always getting up and going again. When we went back inside, I allowed her to sit outside the basket and a couple of times she got up, wandered through the house and back out to the garden again.

After bringing her back from the garden, I put her back in the basket as it was almost time to put the other chickens to bed. But she wasn't having any of that. She jumped onto the side of the basket, where she sat for a while, jumped off and headed for the garden again. That was the sign for me. She was better and ready to join the other girls in the coop again!

Snooky managed to get to the second rung of the roost!

When I opened up for everybody this morning, they all ran into the garden, with Snooky in the lead! Yay!!

Snooky is still not 100% and I often see her stumble or have a slight wobble, and I'm not sure if she will ever recover fully, but I am so grateful that she's improved to the point where she can carry on with her normal life en enjoy the friendship of her companions. As to whether it was Avian Botulism or not I might never know but it has taught me two things - patience is always rewarded and don't under-estimate the will of a chicken that wants to sand bath!

The dustbin chicks

One of Solly’s hens (one of only 4 left after a mysterious disease killed about 20 of his chickens) hatched out six little chicks, leaving another 11 eggs un-hatched when she left the nest at about 6am. About an hour later, I saw a tiny chick stumbling from the nest, still wet from emerging from the egg. Mommy and her crew of six had already disappeared somewhere into the garden, so once again I had a little chick to tend to.

Dottie

I brought her inside and kept her warm in a basket of grass with a hot water bottle and a towel throughout the day and that night. Early the next morning I saw Mommy and her babies just outside my studio window and quickly rushed outside with Dottie (she has two little black dots on her head) and put her down in front of Mommy, who immediately clucked encouragingly and little Dottie quickly responded by running towards her and under her warm tummy.

I kept watch for about an hour until I was satisfied that she was able to keep up with the rest of the clan, feeling relieved that it had all worked out well. Sometimes chicks imprint on me too quickly or the mother refuses to take it back, then it’s a case of looking after a little chick for many weeks before it is ready to join my girls in the garden. Over the past two days they've all grown in leaps and bounds and Mommy is an absolutely perfect mother, calling them to the food I put out and first letting them have their fill before she has anything herself.

Mommy calling the chicks for a tit-bit 

Now, here's the thing. On Tuesday afternoon we disposed of all the other eggs that were left over and threw them in the dustbin in the back yard. This morning, it's now 2 days later, as I passed the dustbin, I heard peeping! Looking inside, I saw that two chicks had hatched. I was gob-smacked! Upon closer inspection of the rest of the eggs, I noticed that one had a hole in it and heard peeping coming from within. I gathered up the two babies and the egg and rushed inside, immediately getting the two chicks onto a towel with a hot water battle. The egg was still peeping, so I carefully removed all the shell and found a perfectly formed little chick struggling to get out. I gently cleaned it and also put in on the hot water bottle with the other two chicks.

The chick in the centre (Snoodles) is the one I took out of the egg

I constantly checked the temperature inside the towel to make sure it was not too hot also often stroking the third little chick and talking to it. After about half-an-hour it raised it's little head and opened its eyes! I was thrilled! It also struggled up to stand, stretching its little legs for a second or two before settling down between the other two chicks again.

After about four hours it was dry and quite alert, moving about and taking an interest in its surroundings, snuggling close to the other two.

I'm thinking that maybe, just maybe, Mommy will accept the two older little dustbin chicks but the one I took out of the egg still has a long way to go and I doubt that it will be able to keep up with the much older chicks, so it looks like I've got a few weeks ahead of me tending to this little one.

Hens lay eggs over a period of time and sometimes those laid first, hatch first. When she left the nest, some of the other eggs might have been on the point of hatching and I think the dustbin acted like an incubator, it was standing in the morning sun with the lid on and it was quite warm inside. If she had stayed on the eggs just a day later, probably some more would have hatched.

UP-DATE Fri 29th Nov 2013 5.15am

Well, I put the first two dustbin chicks back with their Mommy this morning and she accepted them immediately. Of course they were cold and she immediately called them under her warm feathers. I will keep an eye on them today to make sure they keep up with the rest of the crowd. The third little chick which I took out of the egg is still a bit weak, maybe tomorrow...

M.I.A. because of lost chicks

I've been 'missing-in-action' for a couple of weeks and it's all summer's fault! Everybody is broody and  Solly's chickens have been hatching babies like mad, but the heavy rains and predators have been taking their toll. One of his hens hatched six little chicks but within a few days there were only two left.
.

I suspect a stray cat which I spot every now and then, skulking in the bushes and behind tyres in the workshop, but have never managed to befriend it so that I can catch it and take it to the S.P.C.A. Then, to top it all, the mother suddenly abandoned the two chicks and I found them woefully calling under one of the shrubs in the garden. I managed to catch them, fast and wild they are! and brought them inside and, to my delight, within the hour they thought I was their Mommy! I didn't expect imprinting to happen so fast as they were already almost a week old.
.

 

Their Mommy did a good job of teaching them to eat the corn and seeds I put out for Solly's chickens every day because they immediately took to eating and drinking some water after I showed them where it was.

 

After having their fill, it was time to settle down for a quick preen and a bit of a roost.
.

 

Then a couple of days later, another one of Solly's hens hatched five of the cutest little chicks, but by the next day there were only four left, the little black one at the bottom of the photograph being gone.

Early one morning at about 5.30am, in pouring rain, I heard the panicky calling of a little chick and upon investigating, I saw one of her little black chicks all alone in the grass outside the garden, soaking wet and close to collapse - the mother and other chicks were nowhere in sight. I rushed out into the rain, collected it and rushed back, drying it off and cupping it in my warm hand while I prepared a hot water bottle for the basket. It soon warmed up and within half-an-hour it was preening itself and looking around.

 ::

Solly's chickens do have a coop but they are REALLY free-range with only a few of them choosing to sleep in the coop, the rest wander and nest all over our property. I normally try not to interfere with 'nature', but it's impossible for me to see a lost chick and not to rescue it...

So there you have it, taking care of little demanding chicks didn't leave me much time to get round to blogging, it's like being a young mother all over again!

Up-date - The same day I found the little black chick, and still pouring with rain, later in the morning I saw the Mommy and her three other chicks having some seeds outside my Studio, so I rushed out, put the black baby down and she fairly attacked me, gathered the baby under her wing and then herded them all to safety under a canopy and out of the rain. Whoot whoot! Another happy ending and one less baby to take care of! To date, all four are still safe and have grown into beautiful healthy little chicks!

The first two are still in my care, having gotten used to the routine of sleeping in their basket every night and being let out into the garden in the morning, calling when they miss me and following me back to my Studio for a rest and some roosting. I've also taught them the route to the bathroom court-yard garden and every now and then they wander over there for a scratch and a sand-bath. But it's a full-time job and I'm just now catching a breather as they prefer to be in the garden scratching around with the other chickens. Seems they will be joining my girls in the coop shortly...
