I have a 23 week old salmon faverolle rooster who can free range with the other chickens, but he stays in the coop and run. He had been bullied by our head roo who was raised with him, but he started running him off to hide in nest boxes, corners, etc. We pulled the other roos out except the faverolle 2 weeks ago, but he has never developed courage to hang with the others. When I bring him out, another hen will peck him and run him off. I have posted weeks ago about this, but wanted some suggestions after making changes. He has me wondering if he has some deep psychological problem now, because this was the most friendly and outgoing of our chickens a few months ago.
