1. Must we cut out the core in order for the Bumblefoot to go away? 2. After a duck goes lame from the Bumblefoot, is it reversible? 3. Biggleswade appears to be losing his skin on his feet. We are finding orange pieces in his wrappings. Is this caused by too much Epsom salt in the soaking water, or what? 4. Two contributors to Bumblefoot that I've read about are hard-packed ground and wire flooring. We have both. I have paths among native plants and raised beds of herbs. My neighbor, with whom I share the ducks, has 1/2 yard of (trampled) grass & 1/2 dirt. There is too much shade to grow grass. We are in small 1920's urban lots. Are we perpetually sunk with these environs? [We have put hay down on the coop floor for the last several days now.] Re: question 1. We have tried in order: oregano oil in coconut oil, diatomaceous earth, nix-all, vetericyn and neosporin. We are newbie owners of 7 Ancona ducks who are 6 months old. Thank you, thank you for any guidance.
