Hello, my 1 year old duck has had a limp for a couple weeks but has had no scab or open wound. I left on vacation and the care giver noticed that his other leg was swollen. I came home today and looked at his foot. It has a scab the size of a ping pong ball and is extremely swollen. He is very clumsy and falls down all the time, I assume he tripped and hurt his foot. Please help, he won't walk he just lays down... I don't know what to do. I am going to try epsom salt, and maybe colorless iodine. I already tried to put bacitracin on it but he immediately gets it dirty. My dad also won't let me bring him inside, so I might put him in a clean box outside. Someone please advise me on what to do!
