Chickens mysteriously dying!!!!! 😠
Featured Stories on BackYard Chickens
When mine passed it was very sudden. They would show signs and the next day were dead, unless we put them down on our own.
What is the timeline on your loss? (How many in what period of time).
Do they free range?
Is there anything toxic that you can think of that they have gotten into, rotten moldy foods/scraps, something dead, etc.?
Marek's is always a possibility, but they don't normally just "suddenly die", they will generally show some symptoms that you should notice before death.
I do highly recommend that you send one for necropsy to help determine what is going on, you can contact your vet for help or your state lab, there is some info below to help you get started.
If you are losing that many in such a short period of time then I highly recommend that you send one for necropsy.
Also a dose of Corid may be helpful even though you are using medicated feed (which just has a very small amount of amprollium in it). Corid is very gentle so it won't hurt just in case your problem is Cocci. Not all strains of Cocci show bloody stools.
Dosage for Cocci is 1 1/2 teaspoons Corid powder per gallon or 2 teaspoons of 9.6% Corid liquid per gallon
Give for 5-7 days - make sure this is the ONLY water available during that time period. Mix a fresh batch at least once a day.

I lost 4 yesterday morning and 2 this morning. Its been happening for about 4 or 5 days. I moved them to their own pen outside at about 9 weeks old. They don't free range so I make sure they have what they need and there's nothing for them to get into. I just noticed today I have one that was standing and sleeping by itself after eating. It didn't not eat as much as usual.
I think necropsies are free inTN. Probably a good idea to have one done.
