Hello, I am new today to this forum. I posted earlier today and if I am doing this wrong, please forgive me. I have a chicken that is about 5 years old, still lays, is eating, drinking, scratching, all the stuff the other chickens do. The problem is she stands still and pecks and forages, but when she starts to move or walk, she wobbles, and basically falls over like she has been drinking. I don't see any physically injuries, she seems to be acting normal, except the falling. Has anyone ever experienced this before? She can't keep her balance. When she is nervous or if the other chickens pick on her as they know something is wrong she sometimes opens her mouth as if she is hot? Not sure what this is all about but if anyone has seen this and can help, I would be very grateful. She is in the house right now because they were all after her.
