My 9 mont old Maran seemed to have hurt her wing or her leg a few days ago. I was a way for a few days and had someone else care for her but when I got back problem seemed to have got much worse. She cannot really walk now and is just sits there and stumbles over if she does try to walk. It seems like her legs can't take the weight of her body anymore. She also streches her neck and opens her mouth a bit does this mean she is in pain. Please help as these are my first two hens and don't know what to do.
