We got a rooster and I really don't want him to end up a bully! What are your roosters like? Do they run at you? Do they take care of your hens, or just lord over them? Are any of them very sweet? Our little Mr. Incredible (6 1/2 weeks now) is very tame and friendly, if a little quiet, actually. Does personality as a chick carry over at all into adulthood?
