my adopted Polish girl, Miss Muppet, was left for dead after her feet frost bit this last winter. She has since developed gangrene in her feet and shanks. I've been treating her with peroxide soaks, anti bact. cream and a medicated tar solution. They still get hot and swollen and she has already lost some digits. Is there anything else I can do for her. I read amputation is one way to deal with it and I'm not adverse to the idea. Any other suggestions. She's a trooper and very brave and I don't want to put her down. When she feels ok she still lays eggs and is the "egg mother" of one of my chicks. Any ideas?
