I hope those of you with bumblefoot experience will weigh in here. This is a pic of the foot of my 5 year old Cochin bantam roo. This started as a grape sized lump on the top of his foot, more or less between two of his toes. It has never had a black spot/core. I soaked in epsom salts, wrapped it and put him on anitbiotics. There was not much change in the lump, but he did stop limping, so I put him back out in his pen. Several weeks later he was limping again and the lump had doubled in size. I soaked again and this time tried to open it up a little, resulting in the scab you can see on it. Nothing came out but blood. I put a sugardine wrap on it this time and left it for a few days. When I took this wrap off, it had again doubled in size. The lump itself is kind of soft now although it was quite hard to begin with. I took him to an avian vet this morning who felt that this is NOT bumblefoot, but is a tumor of some sort. Identifying the type with pathology would be too expensive. She put a needle into it to see if anything came out and also just got blood. She put him on metacam to relieve swelling/pain and felt that this would become unmanageable within a couple of weeks and I'd have to put him down. I have no desire to cut into a tumor on his foot, but does anyone want to weigh in on whether or not this could possibly be a huge swelling from bumblefoot. The vet did not feel that bumbles get this big, and that given its location and his age, concluded it is a tumor of some sort. thanks for any input.
