My bad one fights anything and doesn't learn. I got him as a day old. He attacks every time someone goes in the coop, so he is in one that I don't have to go into to feed and water him. If I do he will keep trying to spur me no matter how many times I fight him off. He's particularly bad when your back is turned, and I got sick of having to watch out the whole time I was in with flock. He's noisy too. He grew up with several roosters: a Buff Orpington, a standard Silver Laced Cochin, and a D'Uccle. He does not get along with any of them, but I can house the three together without problems. I think the aggression is partly because of the head feathering; they can't see danger approaching as easily as most, so seem to be paranoid. The hens are flighty but not mean. They're the one breed I keep that I would not have around children.
