Some of you read about my Muscovy Drake's ear infection a while back. well everyone was getting to free rnage 24/7 and so he was bathing constantly in the creek...the ear was finally looking better, almost completely healed up, I could see down inside his ear and everything, there was just a bit of dry gunk left. We had a pack of Coyotes wandering around so everyone got put back in the pens and have been there for the last 2 days. I am sure all you duck keepers know how hard it is to keep pools clean and especially hard with 19 ducks & freezing weather. I checked his ear today and it was TERRIBLE, draining and smelly. i got a lot of stuff out of it and put a couple ear drops in and sent him on his way to the creek with the others. The Vet determined it was a yeast infections so the drops are for just that, i did oral(water) meds, but neither seemed to help much. the clean creek water is what reall seems to do it but I am not able to let him free range constantly, what can i do for him?? has anyone ever dealt with a stubborn ear infection like this before? Also, his sisters left ear fully cleared up while they were free ranging, hers wasn't quite as bad as his though.
