My wellsummer had bad bumblefoot on one foot. I soaked her, wrapped her, but never cut. she even had a bump appear on the top of her foot. Unfortunately, during that time(last summer_) we had tons of rain and the coop was surrounded by water. for them to get out they had to wade thru water. was hard to keep it dry, tried vet wrap with duct tape over it. I finally gave up and a year later, she is fine, the swelling on the top of ft disappeared on its own. i am sure she has a spot on bottom of foot, but I do not care
