I have been reading on backyardchickens.com about bumblefoot in chickens. I saw some signs of it on my hen and took action. She didn't have the "black" or "dark hole/sore" on the pad of her foot but she does have like a wart on top of her foot and swelling/warmness on her foot pad. I gave her a shot of penecillian but now she is limping more than she was before. It's almost like she is stumbling and having more trouble than before. Did I do more damage then help? Or will she come out of it within time? I need feedback/advice.... Thanks
