My silver rooster as a chick was held and petted often by my GF (she thought he was a she). He has been the head of the flock since 4 months old, he will not let her get anywhere near him, my on the other hand he will challenge me, but I think he is jealous of the girls around me at feeding time. I have a wire cage I set over him when he is doing this. (currently in a breading unit) This guy is half bantam silkie (stood 6" in full crow) and half blue Ameraucana.
My black rooster (son of silver and a blk australorp/EE) follows me like a puppy dog all the while talking to the girls, or maybe to me IDK,,, either way he has never shown aggression to me or anyone else. Look out food dish!
