I am a wildlife rehabber. I mostly do wild animals but take in a few domestics that have been released. They very often get in trouble out there. Right now I took in a wild Mallard make limping badly. No injuries I can find but he is missing the big foot pad at the base of his foot. No injury there just no pad. He has a very hard time walking because of it. Will this pad rejenerate . What can I do to help him?
