We have a six month old Golden Comet Rooster and 13 Bard Rock pullets ( 12 weeks old) who have been living together peacefully and happily all summer. The rooster has recently shown his ugly side and attacked our 3 year old son. Since then I have kept him locked in the run all day while the BRs continue to free-range. I let him out a couple of hours before dusk ( when we are inside for the night), he free-ranges with the girls and then they all go in their coop together for the night. My question is, can this possibly be a long term solution? I feel very guilty about locking him up. Maybe he would be better off in another home? I have tried with no luck to re-home him, and I don't want to kill him. We do have three other chickens in a separate coop two hens and a sweet BR rooster, the 13 BR pullets hang out with them most of the day.
