Hello... First, thank you for your help. We have a rooster that was on our property when we first moved here. We believe he is about 8 years old. Last year he had a swollen foot, which opened and bled. He was unable to put weight on it without being in apparent pain. Then out of nowhere the swelling went down and he was better. Now it has reappeared and seems to have gotten much worse? We have tried taking him inside and washing it out. We applied blue kote antiseptic while giving him tetracycline. There was no real improvement. It seems like he has scabs on the wound, but not black that we noticed. There are multiple openings that are bleeding. We are thinking it is bumble foot? Here is a picture of the wound, can you please help?
