Well, we had two or three visits, I think it was over $100, the last one we didnt do anything besides put her down, it was$40.
My friend has successfully treated bumblefoot int he past, though I have never whed her do it so not sure how. I like you, cut open the foot (on this last chicken I tried it on) and all I got was blood, I never saw anything. That bird had it for over a year. What I see is when you look at the pad of the foot, there is a plug like thing. If you pick that off it bleeds like mad. The pad gets swollen and hard. I was NPIP testing the birds this weekend and noticed all my large fowl have these on their feet, though none are swollen or sore. It really makes me think its more of a callous than anything else. My friend had her bird get a piece of corn in her foot infecting it. I do not feed corn or scratch here. I think its from jumping off the roosts, though there is nothing sharp or dangerous in there for them, the coop is 6 years old and roosts are well worn. Highest roost is about 3ft off ground.
On the really bad case I had (the one that went to the vet) hers was already open and oozing, and I did find a large mass of something. But that case, it already was down to the bone and all. We were soaking and washing it and cleaning it every day and wrapping in gauze. We even had a foam shoe made by the vet to let air get to it from underneath to help dry it out.
It was nasty.
