Many nice Roosters....I never chance aggressive behaviour...Turn your back or do something he deans wrong and he will attack again...It's been a few months and it's always either off or on with him. He's unpredictable but such a good boy for the girls. He's often with the single girl who is off foraging alone. We heard a noise in the direction of the coop and he went running to check on the girls in there. I'm reluctant to get rid of him for these reasons and hope he will chill out.
