This morning I went to the coop to let the girls out, and found my poor Elli trapped underneath the door that closes off the nesting box. It's not a very heavy door, it's just chicken wire in a frame,but I guess it was enough to pin her down. When I took her out and set her on the ground,she flopped right over. I've brought her inside and she's now propped up with some towels in a crate. Each time I let her try to walk she falls over, as if her legs keep giving out. This is the chicken that we've suspected has leg problems,though. She's always had a hard time getting up from sitting positions and she can not stand to have nothing underneath her feet (such as when we pick her up). She doesn't seem to be in pain,but she can't walk. What should I do to help her? Will this go away on it's own?
