I adopted 3 fully grown bantam hens, adding to my flock of 5. They are in very bad condition and extremely aggressive. They have no feathers on their feet and missing plenty of nails. This particular hen cannot walk. It seems like her feet are undefined masses of bone ( its as hard as bone). My flock is very spoilt and in excellent condition, but these come from a home where they were in mud most of the time. I tried washing her feet in luke warm water but it doesnt look like anything is coming off. I dont want my hens to be in pain, and I would appreciate any help I can get!
