Also if you have a vet close by ask them if they will treat a duck or know anything about them, maybe some vets that treat farm animals will have some knowledge or can look it up on how to treat. How is she acting this afternoon, and I just came in and found a message from a BYC member I had asked her about what antibiotic would be used for this she rec. Tylan 200 it can be bought at feed stores.I live in Cleveland MS and I have no idea where any avian vets are around here. There is one about 2 and a half hours away from here that I call when Quackers had bumble foot and they said they had a doctor that did waterfowl (ducks) but I don't know if he is going to be in on Monday. I guess I will call them tomorrow and ask. If he is then I will take her up there.
