I got a new hen. She seems healthy and fine, she's a bit younger then my other girls and she came from a home where she lived on wire mesh for the flooring. She's a little shy and tend to stay away from the other hens right now, although they don't appear to be picking on her. I've been keeping a close eye on them. I've noticed that she has kind of wobbly legs. She doesn't seem to favor one leg over the other, but she always seems to be almost shacking or trying to balance like her legs are weak or something. I've never seen her roost, I'm not sure she knows how to since she never had a roost before. Does anyone know what could be wrong with her? Or what I can do to help her?
