I had a very educational experience with what is generally thought of as bumblefoot in turkeys and it was very valuable so I wanted to share it with everyone here. I took Christmas to an exotic bird hospital because our dog vet recommended them. The three vets with avian experience also consulted a poultry specialist on the other side of the country. All of the vets were very interested in the problem and went to great lengths to explain to me what the issues were. This is what I learned: Bumblefoot in turkeys is usually not "true" bumblefoot". It is actually pressure necrosis. This is caused by the fact that the birds are bred to be top heavy (as we all know) which causes swelling from the fact that the feet are not meant to carry that weight. There is not necessarily an initial bacterial infection which causes pressure necrosis. My turkey's fluid sample did not show a bacterial infection. However one will eventually develop. Edited to say: the fluid in my turkey's swelling was mostly joint fluid. Oral antibiotics are useless because the the blood circulation is so poor that the antibiotics don't make it to the foot. The antibiotic must be a topical one applied directly to the foot, preferably one which is absorbed through the skin. This means that the person should wear gloves for this procedure. Keep the turkey on as soft a surface as possible. This will relieve the pressure on the feet. Do not keep the turkey on hardwood shavings. These drive splinters in the feet and exacerbate the problem. I will update this post as I find out more.
