We have a rooster who is favoring one of his feet. It's very swollen and apparently tender because if he can avoid it he won't even put it on the ground. We brought him in today, prepared to do bumblefoot surgery, which we have never had to do before. After soaking his feet for several minutes and cleaning them, we were unable to see any scab. The swollen pad on the bottom of his foot is very hard and tender because he reacts when you apply any pressure there. The back toe on that foot is also swollen and it looks like the claw has broken off. So how do you treat bumblefoot without a scab?
