I am concerned about two of my roosters. All of my chickens are young, only 7 months old, so I don't know if that has anything to do with it. 1. My Sultan rooster doesn't like any of the hens. He prefers one of my Cochin roosters. The Cochin wants nothing to do with him as he has a favorite lady. 2. One of my Silkie roosters mounts my hens heads instead of where he is suppose to. Has anyone else had such odd behavior from their roosters?
