We have two young roos, both about 9 months old, over 23 various breeds of hens. They both get along Ok and tolerate people well enough. We have them to keep an eye out for hawks and other predators, and they do a decent job of it. The only problem I'm having is that they tend to over breed our hens. Poor girls are losing feathers off their backs and the back of their heads. Is this something the boys will settle down on as they mature? Or should I be looking for a couple of new, gentle flock managers?
