My sister recently purchased 2 ducks for Easter we aren't sure whether they are male or female. But about 3 days ago the larger duck stopped walking, it wobbles around to get to its food but won't go far. It plays in the pool but not for long either. We noticed blood on it and figured it was from the other duck poking at it so we bought it Blue-Kote for the wounds. It's still limping and we noticed that it lost its appetite. We were going to take it to the vet but our local vet has never treated ducks before. I read that it may be lacking vitamins, any advice will help. Thanks!
