How a flock is raised is as important as genetics in determining temperament, so how you raise the chicks will have a large effect on the friendliness of your birds. A flock that receives positive human interaction from day one is more likely to be friendly than a flock with only sporadic human interaction. When we select our breeders, we AVOID SELECTING aggressive males. Even so, a good male will be predisposed to protect the flock. So, if he thinks you are acting like a predator or sees you as a threat, he will likely challenge you.
