Hen died yesterday following short sudden illness - any ideas?

Firstly, I hope I am posting in the right place.

I had a small flock of 4 bantam hens and one cockerel. The hens are mixed thorough breeds; Silkie, booted bantam and two welbar bantams, and the cockerel is a mix breed. They are all just about 11 months old.

Yesterday, I found our silver welbar Stella stood quite still and “panting”. It was a hot day, and I know that chickens can ‘pant’ on occasion when they are hot, but she was outside in the shade panting and not making any attempt to move. They are all friendly, but I picked her up after watching for a couple of minutes realising something was wrong. I placed her by the water bowl and she took a couple of sips but again made no attempt to move.

I brought her into the house being a bit cooler inside. She stood on a towel still seemingly panting, but I think that was just how she was breathing. She took a few steps and did a poo but didn’t go exploring like she normally would. The poo was normal and fairly solid. She was very lethargic and just stayed wherever you put her. She hadn’t made any noise in this time and wouldn’t eat or drink (not even a grape which were favourites). She eventually lay down and then her head started to drop to the floor. Towards the end, she was shaking quite a bit. I would say she had 3 or 4 bouts of shaking in about half an hour.

I called a vet, but she didn’t make it. She only lasted about an hour since bringing her inside. I am glad it was quite sudden and she didn’t suffer for long but does anyone have any ideas what could be the cause?

I couldn’t find any signs of any injuries, mites, fleas, worms, egg binding, or anything else unusual. She had laid just the day before. She had been our cockerels favourite for a time so she had feathers missing from her back and neck that we were keeping an eye on and were starting to grow back. She was bottom of the pecking order, but again, we always let an eye out that she wasn’t being bullied.

The others in the flock seem fine, although slightly out of sorts now Stella is gone, plus our Silkie Jet is broody.

Any thoughts or help would be appreciated as I don’t know whether to be concerned about the others. Photo of Stella nesting just last week, being watched by Vera the booted bantam.

No unfortunately nothing. There doesn’t seem to be any indication from the other chickens, and I didn’t fancy cutting Stella open.
The only thing that seemed apparent was the missing feathers on her back from our cockerel, and looking back I now wonder if she had scaly leg mites as her scales were slightly lifted at the inside of her ‘ankle’. But I can’t see that either of those would cause death.
How much does/can stress affect chickens? I don’t know if Stella was stressed... but I’m finding that the cockerel and two hens who are out free ranging (the other being broody) are quite needy at the moment (hanging round the house a lot).
 
:hugs I’m so sorry! The only way to know for sure is having a necropsy done. If it happens again you can consider sending to your state lab. They usually don’t cost much but sure can be good to know what’s going on. Hopefully someone with more experience than I have can tell you if the seizure like activity is indicative of something.
 
Thanks... yes that’s what I was wondering. Or the seeming ‘panting’? I wasn’t sure if the seizure / shaking was just a sign of it being the end?
Thanks for getting back. I’m in the UK and we have buried her now, and at least there have been no signs of any of the others having issues.
 
I'm so sorry to hear that you lost your Stella. I was on to post an almost identical story about my 8-month old
Egyptian fayoumi that passed away early this morning. Only signs were lethargy and only taking water. I am trained in mammalian necropsy and vertebrate dissection, so I'm thinking of doing one to see if parasites or GI blockage might be present. Other than that I put corid in drinking water to treat my other girls. Fingers crossed that none of your others get sick!
 
Sorry to hear about your loss. And only a pullet too 😔 I’d be interested to know if you found anything if you do decide to do a necropsy.
I saw Stella take a couple of sips of water after putting her by the water bowl before I brought her inside, but once inside she wouldn’t drink anymore.
What is corid? I have added a few drops of pure apple cider vinegar to our flock’s water now, but they seem to prefer to drink out of dirty puddles 🤷🏽‍♀️
The only other thing I haven’t mentioned about Stella is that she was bottom of the pecking order... plus with being the cockerels favourite... it did cross my mind maybe she was stressed. Although she certainly seemed to get on just fine being a free ranging chicken. Nicknamed “the digger” for always being in a plant pot or turning up earth looking for worms!
 
Hi Rachnicko,

Corid is an anti-parasite powder or liquid that you can put in the drinker to dose the chickens for prevention or treatment of coccidia, a common parasite naturally occurs in soil/the environment. Chicks are extremely susceptible and adults can get it as well. It can pass from bird to bird very easily via fecal transfer. One of the telltale signs is dark tarry poop and chicks can decline rapidly (dying within hours of noticeable symptoms). Search for coccidia or coccidiosis in the forum. Tons of info there. Corid is very easy to use and works wonders, however, if treated in time or used as a preventative (although I don't usually do prevention over winter and hadn't done it yet this spring).

This is my first experience with illness in a pullet. 😥 She didn't have tarry stool. I did perform a necropsy and there was nothing remarkable whatsoever. No obstructions, no excess fluids, no visible inflammation or hemorrhaging. No visible work infections in the GI tract (although I did not check the heart and forgot to open the gizzard). This happens often in many necropsies, but it made me feel better that she didn't have a raging condition. . I didn't take samples for pathology, so no further diagnosis possible. Such is life, or, well, death. Others seem fine.

Best to you/yours!

Sounds inconclusive, but thanks for sharing your findings. Thanks for the tips too... I’ve ordered an organic alternative to corid that I found online, and hoping it will be ok (we shouldn’t have to hold back on eggs with it). No signs of any tarry poop, but we have some chicks due to hatch soon so also ordered medicated starter just to be safe as a prevention as you say.
All the best to you and yours too!
