I have 3 hens and 1 Roo with 4 female ducks. The chickens are all silkie mixes. I have a bunch of younger ones in the house 3 are ready to go out they are about the same size as the older one outside, problem is I have 2 immature boys and 1 girl ...I tried one of the boys the other day and my rooster tried to mate with him. I am afraid he is just going to jump on everyone. He is not aggressive but hes never been around another male...so I am afraid of sneaking them in at night..that tatic might not work and I wont be around to supervise. Any thoughts?
