One of my 1/2 grown Pomeranian Geese was found at my pond injuried. His foot is mangled, swollen and she's not putting any weight on it. I brought her up to the barn and soaked in epsom salt and then discovered she has what looks like maggots all over her dirty wet chest (she has been laying in very marsh like humid conditions). I sprayed with hose, still see bugs, so dusted her with a lice powder. Any advice?? I don't see any obvious bleeding injuries, open wounds. Should I use hydrogen peroxide? Please help!
