I also have a CCL roo that is 9 weeks old. He and 2 pullets have been living in a separate coop and have been slowly integrating with the rest of the flock. They seem to be ok with all of the hens, or I should say that the hens are ok with them! They have lots of escape routes, and tend to stay away from the big girls. The 15 weeks pullets do not bother them at all.
Last night I saw the three 9 week olds looking into the main coop as though they wanted to go into it. The 15 week roo heard them and came down the ladder to watch, but didn't do anything. The 9 week olds looked in several times, and then just roosted on branches outside the main coop.
Should I be worried about the larger roo confronting the younger one?
