One of our leghorns has bubblefoot. We noticed she had a bump on the side of her toe. We soaked the foot in water for a while to get it clean and soft. I used a razor blade to cut off the black scab. I tried to dig to see if there was a plug. I don't know if I didn't dig deep enough or what, but didn't see anything that looked like it would dig out. The foot started bleeding, so I didn't want to go any further after that. I applied Neosporine and bandaged the foot. For anyone who has done this before, is it possible that it was not bad enough yet to have a plug and pus. The bump was the size of a garbanzo bean.
