Hi, im new here, so i hope im doing this right. This is my first time owning chickens and ducks. My drake pekin has been having some foot issues. We live in a desert setting and are a little dry where i live. We have a mall kiddie pool for them to swim in. My duck starting with his feet cracking open and bleeding. I wrapped them with gauze vet wrap and kept them as clean as possible. I then leanred of Vetericyn, wound and skin care and bought that to put on his feet. Within a few days his feet cleared up. Yesturday morning my daughter found him stand "like a flamingo" on one foot and is limping around when let out. Sprayed his foot last night and again today and am noticing he has some swelling now. What should i do??!!!
