Island Girl: You say he's 8 months old? While it's said that some roosters tend to mellow after a year or so old, I'd be for culling long before that. My current roo is a nice boy. He's people friendly. Not wanting to be held, or any thing like that. But, he comes around to talk to me when ever I'm outside, and he comes to investigate any one who comes to the house. He won't allow his girls to fight. He accompanies them back and forth to the nest boxes, tid bit's them, lets them eat first. Occasionally will chase one of the girls, but, who's to know who started it, and what goes on in the dating life of chickens? Some of the girls have feather wear, but I think that may be as much a factor of feather quality as aggressive mating. The one time he contemplated being people aggressive was last summer when my 8 y.o. gdtr. ran across the yard squealing. He may have thought she was chasing his girls. Any way, he gave pursuit, and she reacted with fear. I gave her 5 minutes to cool down, then forced her to come out and learn how to herd a chicken. She spent a couple of weeks training him, and he's been a good boy since. The only complaint I have is that he loves to hear his own voice. You've had a good rooster before. So you know what that can look like. Replace him.
