Hello everyone- I need help because I am at my wits end.

I have taken care of /done rehab for chickens for the last 6 years (pigeons for 24 years) and am at a total loss.

I keep having chicks die all from the same symptoms at a 4/10 rate. I have no idea what is going on. I live in Hawaii and my chickens are a combination of wild/domestic. The adults live outside. I give them fake eggs to sit on when they go broody to try to control the flock, but inevitably since they are free range (locked up at night) one or two hens will run into the forest and come out with chicks 21 days later. Sadly most of my hens are terrible moms so I intervene and bring the chicks inside to raise until they are old enough to be ok outside. I clean their cage daily with chlorahexidine, change their papers 2x a day, have a good square heat source over them at the correct height, vitamins in their water, clean their water/food containers with bleach, 18% chick feed- changing their feed and water multiple times a day. I am very vigilant and want to give them the best chance at life.

This spring so many having been dying with the exact same symptoms each time. They are dropping like flies. Usually one or two out of a big clutch might not make it but this is a massacre. It's been horrible. It goes as follows:

1.The chick will start screaming for no reason. I physically put it under the heat house and it still screams.
2. Then legs stop working.
3.Then it becomes totally lethargic, doesn't eat or drink (I have hand fed several but it ends up making no difference)
4. Seisures ongoing until it eventually spasms and dies. Everytime within 24 hours.

At one point the neighbor boy gave me 4 chicks that he found to raise because he doesn't have a setup and his parents don't want chickens. Literally all 4 of them died the next day- same symptoms.

I sent out 5 bodies to get a necropsy from Hawaii Agricultural Dept on Oahu after having no luck finding any vet on my island that would do one for me. They did not find Avian pox and ruled out Mareks. They told me they may have more results for me soon but will be very general as they are only really interested in Avian pox/flu.

Poop is normal, no respitory symptoms. A couple I syringe fed but it made no difference- they still died 25 hours later.

Please help me.

Hi, and welcome to BYC.

I'm sorry about what's going on there with these chicks.

I hatch hundreds and hundreds of chicks, and you're doing more than I am with the daily sterilizing.

When they're so young like this, it's usually not going to be a disease or illness, albeit coccidiosis when they're a few weeks old, but sounds like some type of poisoning to me.

I'm thinking there's something they're breathing or eating that's toxic to them. Are they in your house or in a brooder in an outdoor building? If in your house, are they near your kitchen? Ovens and some non-stick coatings on pots and pans can emit invisible fumes toxic to chicks. Any air cleaners or air fresheners near their brooder?

What are the papers you are using for bedding? Try just paper towels for a while. Can you switch to bottled water just to eliminate that?

What type of heater? If bulb, make sure it's not teflon.
 
I agree with it sounding like potential poisoning. Could they be getting into something they aren't supposed to or given something they aren't supposed to?

Thank you so much❤️ I appreciate your help so much. Before I posted this I had that thought for the first time today- could this be poisoning? I have no idea what it could be though that could be poisoning them..the cage is located in my storage room and everything I have in there is kept in closed bins. I don't spray anything like pesticides. I thought maybe it could be the cage- since it is old and has some rust (waiting to have no chicks to finally take it apart and derust it) but at the same time I don't think it could be that because this exact same thing happened with the batch I had sent out to the Ag Department and they were situated in a plastic bin with the puppy pad papers I changed daily. The puppy pads are from Costco. I don't think it could be gas or anything because I don't have any natural gas/propane in my house. Several of the chicks who died I took hours after hatching while they were still under mom- so they had no chance to injest anything. Their feed doesn't have any visible mold. I cleaned the nest boxes with chlorahexidine and put new straw in them right before the last chick I took right from the mom died. The only thing I can think of is to move them to another room and see if that changes anything- but it just seems so strange- I can't think of anything that they would be exposed to in that room to create a problem. It's always seisures ongoing before they die so it does seem plausible it's something affecting their spinal cord or poisoning. No visible poop issues- it looks super normal.

The heater I have is one of those square ones where you can affect the height. I have it so that it is shorter towards the back than the front since I have both Serama chicks and regular chicks.

The chicks all die within 7 days old.

Thanks again for all your help❤️

I can't think of anything but am definitely open to ideas. I have them in my storage room where I have all my stuff in bins on storage shelves. They are in a big cage that does have some rust- but before this cage I had the same death issue while the chicks lived in a big plastic bin with a puppy pad underneath. In this big cage I have puppy pad liners and one side I have a puppy bad ontop so that they have some insulation underneath the heater (not just the wire grates). I change that 1-2x a day. Food and water are in containers in the cage.

Could it be my water? I live on catchment. Me and all my animals have no issues drinking it but maybe I wonder if it could be an issue? Then again if it was- wouldn't I see poop issues with the chicks? Their poops look healthy.

Thanks so much for your help❤️
 
To me it appears to be a chemical poisoning from the excessive use of bleach and chlorhexidine. The heat lamps will cause toxic fumes.

I would stop the excessive cleaning with chlorix etc. as it can result toxic for the chicks.

Use apple cider vinegar instead and just simple old towels or bedsheets for the first week, then change to soft wood chips and sand.

Very sorry you lost so many.:hugs

Maybe try and leave the next clutch of chicks with their mother. The ones that will survive shall be very resilient.
 
Yeah +1 for too much bleach and chlorhexidine. I know that's not what you want to hear.

Factor in that chickens will drink from poopy, muddy water when there is clean water right next to them.

Pump the breaks on trying to protect them so much, and maybe skip bleach and chlorhexidine for awhile. Just use some soap and water, maybe some vinegar. A little dirt and poop isn't going to hurt them so long as you get most of the obvious icky stuff.
 
Me three… please stop with the bleach and chlorhexidine, sounds like poisoning- I have had clients with similar issues. Your routine (while best intentions) sounds like chemical poisoning waiting to happen, and could very well be the reason your chickens are dying.

Also, check the puppy pads you’re using — many are scented or treated with chemicals to attract puppies or control odors, which can be toxic if ingested or even just from prolonged contact. Chickens peck at everything, and absorb chemicals through their feet too.

Try switching to a more natural, bird-safe cleaning routine: plain water, mild soap if needed, good rinse on plastics (which will also hold chemicals indefinitely), and good ventilation. Bedding should be clean and chemical-free — no perfumes, no antimicrobial additives, nothing "extra." Sometimes it’s the very things meant to keep an area “sanitary” that end up harming sensitive birds.

How inbred are the birds? This can lower their immune system and also tolerances to substances.

Edit: I re-read the post...also the heater... heaters that are not made for birds emit very serious toxic fumes. You cant even use a space heater for parrots- seizures and death is slow and painful. Those droppings are not normal. They seems to have undigested small seeds- what are they eating?

Hey there thanks so much! So I only started the chorahexidine and bleach routine after so many died in the first batch. Before that I was only doing soap and water and in the past have found those work fine. So not sure since this happened both before and after that routine this spring. In terms of the puppy pads I just checked and they are not scented. There is a layer inside of them that collects the liquid, but I looked at the used one tonight from the cage and there are no pecking holes. Here is a link to the pads:

I am starting to worry it may be my water. I am boiling my water to give to them tonight and am going to start buying drinking water tommorow. I live on catchment and this is the only thing I can think of after ruling all the other stuff out.

Definitely some inbreeding with the seramas and possible inbreeding with some members of my flock- but then again I have like 50 chickens and at least 30 are roosters. The seramas I know this can be an issue- as the lady that I bought them from told me she's had a lot of problems breeding hers. But the other regular chicks are dying at the same rate and that neighbor boy brought me his 4 which are from a wild chicken couple (not a huge chance of inbreeding in that case). Thanks again❤️
