After reading many stories of nasty roosters, I'm beginning to doubt my decision to keep one - I have two small children and would like to let my hens and rooster free range if it is safe. Are Silkie roosters likely to get nasty? He is only about 5 or so months old so far, and is showing no signs of agression. He will get between me and his girls when I come near the pen, but if I reach in or come into the pen he runs from me. Is there a way to keep him from becoming aggressive?
