I got Chuck with my first flock of 50 almost 3 years ago. Since then I have added 3 more flocks totally give or take 70-80 chickens. He has been my only rooster. He is not real friendly, but not aggressive either. He treats his hens with reasonable care. Once in a while he will get pushy and peck at one of them that is bugging him. He does his job, alerting all to any potential danger.I would feel a little sorry for him because we free range, and 70 chickens take off in all directions and he tries hard to keep an eye on all of them. In May I agreed to take 4 chicks that the school hatched as a science project and didn't know what to do with once school was out for the summer. (They were born in April). I thought "great" 4 more egg layers. Wrong!!!!!. 3 roosters and 1 hen. All four have always hung together and are very friendly. I can pick them up , love up on them, etc.Chuck isn't bother by them. He could have taken them out a long time ago when they were chicks. When I give them treats, they are all together and are not aggressive at all.Currently there is no acts of aggression. My kids tell me that they will eventually fight until death. My question is should I separate them? Re home all of them, or 2 or wait until I see some aggression. Is it possible that they will live in harmony or is that a pipe dream?
