Hi, I have 2, 3.5 month old barred rocks in my flock of 17 ( various breeds). When I first got them one was quiet and keep to herself. Last few days though the other one has been acting strangely. She is normally active and forages with the rest of the flock. She is still eating and drinking but otherwise stands, with wings down and head tucked sleeping. She does not seem as strong on her legs as she should be. The last few nights I have noticed that the 2 of them have not been perching with the rest of the flock. I noted the "ill" one tries to get under the other ones wing. Almost hiding. They live in a large coop and have had access outside to forage and play for about the last week and a half. Could she have eaten something she shouldnt have??Any help would be appreciated. This is only my second month raising chickens and I am loving it.
