I have a male Pekin. He seems to need a mate because he keeps trying to mate with my hens and they are missing feathers on the backs of their necks where he grabs them. I do have a rooster who is a buddy of the duck. LOL! I don't know if the duck really wants to mate or if he's just copying the rooster. If I am able to obtain a female Pekin, how would I introduce her to the flock? Will he attack her or will they?
