One of my Madagascar hens lost her legs from frostbite over the winter. One leg is missing from about halfway from the foot to the hock and the other is missing the entire foot. She had been getting around just fine on her hocks but I decided to see if I could give her a more normal life. She is wearing her prosthetics tonight and is using them! I do not have the feet on them yet either. She is now walking upright which she had been unable to do for about 6 months. She seems much happier already. I am going to get some photos of her soon. With and without her prosthetics.
