He's so beautiful! Looks similar to the Easter egg roosters that I've had. I am super busy so I don't have time to read all the posts. I just wanted to say that I currently have a rooster and four of his cockerel sons with three in an adjacent run. Aside from the usual chicken "rape," there are no major problems. Daddy rooster tries to hurt me often while his sons do sometimes. So, with five current roosters (and four in the past), I'm sort of a rooster expert if you want to PM me with specific questions. And no, you can't make him nicer. Separation will work while separated but reintroduction can be a problem. My roosters have been great with their chicks. Also, two of my past roosters gave up their lives defending their girls, one to a hawk and one to a fox. The hawk was because my mother was secretly "letting them out to play" while I was at work. The fox dug in. Since then, I've rebuilt Chickentopia, and a fox is not getting in unless he has wire cutters.
