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. It's been like this for at least a month if not a little more. We gave her a shot of antibiotics we bought at Tractor Supply for livestock but didn't help. I need help please!!!
