I have four Pekin Ducks. They are about 6 months old. I have never had ducks before and I think I have 1 male and 3 females (the only thing I base this on is the drake feather). For the past week Hubby and I have noticed that the girls (?) are biting the neck of the boy (?) and he is loosing feathers there. Every day they chase him, pin him down and bite the back of his neck. Sometimes it is just one on one and sometimes it's two against one. The boy seems a bit smaller. None have laid eggs yet, so I really don't know what I've got. And, I have no idea if this behavior is normal, if the little one is being abused or if it is a prelude to mating. Can someone help me?
