I am getting a new chicken coop for non silkies and I am getting another rooster. The thing is I am getting the rooster from my friend and if I don't go ahead and get it they are going to kill him. The rooster I am getting is a silkie mix and he is 4 to 5 months old. Can I put hime with my four silkie hens and the full blooded silkie rooster until or do I need to keep him separate. Please help!!!
