I have 3 male ducks and one female. One of my male ducks got his foot injured and is hobbling around on it. I have washed his foot and treated it and tried separating him from the flock, but he goes nuts. He is the youngest of the group and I understand they like to show off for the female, but he is taking a beating. I am looking to get some more females but have not had luck yet. What should I do in the meantime?
