I just recently acquired a rescue duck that some one dumped at oure local lake and scenic I got her she has had a limp and if she is not moving around(which is not very often) she lays down but when she walks she drags her tail feathers so I picked her up and looked at her foot and her left leg had what look to be like when a chickens legs gets mites and looks nasty but I kinda touched it and it fell off and her normal skin was showing but she is still trying not to move and I think she still has some on the pad and around the pad of her foot. so I guess my question is if it is ok to soak her foot in epsomes salt(proably spelt it wrong) if not then what can I put on her foot to make it better?. any advice would be greatly apreciated thanks. o by the way she is a Muscovy and right now I have her in my room separate from all the other ducks and geese
