I think I would give him to someone that can confine him in a covered run. I know you love him but, you aren't going to use him for breeding. If he was King of the Coop elsewhere with a harem of hens - he might even forget about" taking off." or be too exhausted to try. Do you know someone who has a predator safe pen with COVER and hens for him - just as a trial to see if it would work?
