Chickens constantly dying

[Noworl21]

So i the past 5 days 13 out of 45 chikens (2 months old) died. First they get like soft(doesnt eat or drink) then they drop and cant walk or use their legs and in the end they have something like epileptic seisure (shakeing violently) and die.

Does anybody know what is it and what can i do about it

I would reach out to your poultry extension to see about getting a necropsy. If another bird dies keep it refrigerated but not frozen and follow their instructions for sending it in. Do let us know what the results are for that

What do their droppings look like? Watery, bloody?

You can treat them for coccidiosis using Amprolium/Corid or a sulfa antibiotic as some coccidia strains di not respond to Amprolium.
Coccidiosis is quite common between the age of 6-12 weeks leaving them weak and tired looking with fluffed up feathers.

Cramped quarters, hot temperatures with high humidity often cause a sudden outburst.

What breed are the chicks?

What do you feed, including treats?

How hot has it been?

Where are they being kept?

I agree, it wouldn't hurt to treat for Coccidiosis.
