We have a BPR (Daisy) that is having a hard time balancing from front to back, has no appetite and walks very deliberately as if she is compensating for an illness. This is the second time she has had an illness. The first illness was last week when she had a allergic reaction. We still do not know what she was allergic to. She had a hard time breathing and her comb turned purplish. The vet gave her a shot and three hours later she was fine. The symptoms she has now are different. This started last night when we noticed that she was the first chicken to roost and she never does that. She was very slow in her actions and her appetite had went to nothing. We have isolated her from the other chickens and the other chickens are normal and healthy. We are keeping an eye on them. She is in her cage now and can barely stand without falling front to back.
