4 month old chickens dying.

[pulp2paper]

Last 3 days I have lost a chicken. Today I have 3 that are walking drunk legged and none of them have food in the craw. But all are drinking. Lost 3 2 weeks ago and started sumlet for 8 days and they all seemed healthy til 3 days ago. Dead bird each day. I wormed them about 8 weeks ago. No new chickens to flock. No mites that I can see.

Sounds like they may have been poisoned. Have they gotten into anything? New foods? Could their feed be moldy?

 

[pulp2paper]

No. They are sick. It's like one got something and gave it to another. Then died. Next day. New sick one. New dead one.

Have they been exposed to a rotting carcus? Could be botulism, or maybe Mareks.

I am not saying it is Mareks but here is a link that describes this disease.

you may one to check with a vet or state agricultural department.

Wishing you the best of luck.

Here is a link to your state vet to send in a refrigerated body for a necropsy to see what the cause of death is: http://www.usaha.org/Portals/6/StateAnimalHealthOfficials.pdf
Coccidiosis, botulism, and moldy feed could be possible causes. Look closely for other symptoms, such as diarrhea, standing around puffed up or hunched, or lameness. Dehydration and heat stress could be a real problem in hot weather. Sorry for your loss.
