About a week ago I noticed that my rooster's foot was badly swollen. I read about bumblefoot so I washed the foot and peeled a scab to see if there was a hard spot but I didn't see one. I put bandages on his foot for a few days after that until the open wound healed and gave him some expired antibiotics but his foot only seems to be swelling more. I have some prednisone. Does anyone know if that would help or what else I can do besides get a vet?
