May need to find a girlfriend for my "extra" duck! I have 2 males and 2 female Blue Swedish ducks, they are about 3 months old. Well, a young mallard flew in and decided to stay. It has been about a month. The other 2 male ducks seem to be chasing him when he gets near the females. They had been getting along fine until lately. I thought if I got him a girl mallard, they might calm down. But then the problem is where to find 1 female mallard!
