No mean rooster gets to reside here, period. I don't have to show my boys who is boss. If I do, then they'll be on the next train to Freezer Camp. Good temperament is largely inherited. They are what they are. Handling them only makes that show itself sooner, meaning he can be the friendliest chick in the bunch, but when the hormones start flowing, he may be comfy enough with you to take you on and challenge you. If it's not in him to be aggressive to people, then you can handle him or not handle him, and it won't make any difference in the outcome.
Aggression toward humans is not tolerated here. I have two Barred Rocks, one Blue Orpington and the Delaware in my avatar, all good boys. I also have an up-and-coming 15 week old blue wheaten Ameraucana cockerel who is just now getting to the point when I'll know if he's going to become aggressive or not, so fingers crossed that Levi doesn't shoot himself in the tail feathers and have to leave.
