Mine had severe bumblefoot but it was on the side, so no scab... I soaked it in Epson salt kept her in for weeks with electrolytes and other poultry meds selenium, vetricyn, iodine, neosporin, etc...finally I had to cut into it. I watched youtube videos which were very helpful. I pulled 6 "corn kernel" things out. I also started giving her penicillin shots. I did 5 days of shots and then a few days later another 3 days. She developed wet feather during this as well. Maybe from not getting in the pond, not free ranging, and the mud of the run. All are causes of wet feather, and all things I subjected her to ignorantly during her convelescence. She is now back with the rest doing great! As far as cutting into the foot, you just have to commit. I thought at first I had wrongly diagnosed hee, because I really had to search for the kernels...but they were there. I hated doing it, but I am glad I've got the experience under my belt.
