I soaked duckies feet in warm water with epsom salts. I started by shaving the top of the callus off. Once I was past the hard skin I cut into the swollen spot dead center of where the black spot was. Nothing but blood. I soaked his feet for another 5 minutes. I tried again this time making the cuts larger so it was more like a +. Just more blood. I cleaned it, packed it with antibiotic ointment and wrapped it with waterproof band aids. He's in the coop for the night, which stays pretty dry. I don't see pus, a plug or anything white. He's been limping, its a swollen lump and the leg feels slightly warm. It did have the black center before I shaved it off. Did I do something wrong? Or should I just resoak and try again in the morning? Thanks!
