I have a bantam mix hen and her legs are messed up quite a bit,she can't walk or fly up on anything well at all. She did have almost an inch of crusty like stuff on the back of her legs and some do have mites which I'm treating them for now. But only her leg is swollen and on her left leg her last toe is curved up and it's very difficult for her to walk,and the roosters breed her and she just lays there on the ground weak like. It kinda looks like bumble foot on her leg cause of the sores. Any help at all would be appreciated!!! Here's a picture of her last year laying an egg.
