I have a chicken who i rescued about a month ago from a shelter after she came in unable to walk. I've been working with her and she was able to stand up and had started walking on her own, seemed like she was getting better. Today she can't get up, her legs keep going out behind her and somewhat out to the side every time she tries. I've felt them and rotated them around, she doesn't act as if it hurts her, no crying out no moving nothing, and it doesn't feel as if it's dislocated or broken or anything. When I got her she saw a vet and he didn't think it was Mareks, and the fact that she has continuously gotten better made it seem more as if that wasn't it. he had thought she had some sort of muscle or nerve damage. has anyone had this happen before??? any ideas? Please??? She's not very old, maybe a couple months, still peeps like a chick and I'd hate to lose her after putting in so much effort getting her better.
