I have a 6 month old that suddenly lost a lot of weight last week. She was lethargic and I couldn’t get her to eat but I got her to drink some. I thought it might be botulism and then coccidiosis but now she has a crooked neck and falls over backwards. I’ve been tube feeding her nutridrench and vitamin e for 4-5 days along with kaytee exact but she doesn’t seem to be getting better. All she wants to do is sleep. Does wry neck make them tired? My other 7 chickens are all fine.
