I'm posting some pictures of my goat's sores he has recently develop on all of his legs near his hoof. My other two goats do not have these sores and I'm wondering if someone might be able to tell me what's causing them? And what I should do about them? I have been cleaning them out with hydrogen peroxide and i'm going to start using a wound powder that I have used previously on my horse. Also there's nothing in their pen that I can think of that would cause these sores. The ground is frozen with ice and snow in most parts but we have been having rain lately so there's mud in areas too.
