Okay, here's my take on it, from raising several breeds, both hatchery and breeder roosters.
If they are programmed to be human-aggressive (and temperament
is heritable, make no mistake!), then handling them as chicks will not make them any different. It only makes them much more comfortable in challenging you when their hormones begin flowing.
If they are genetically easygoing in temperament, handling won't change that when they become teenagers. By handling, I don't mean dressing them in tutus, LOL, just picking them up on occasion to check them over and get them used to being examined, etc. They may bite to test boundaries as "kids" but that is usually handled by grabbing them up and holding their beak shut-they really hate that! Even the rooster in the video below did that at 13-14 weeks of age and two sessions of aversion therapy cured it
because he was not human-aggressive anyway. He's been exemplary ever since and he's over 3 years old now.
Check out the video in this post for proof of what a rooster can be like-this was the teen biter:

He had a half brother who was super friendly as a chick and up until 14 weeks of age, then the aggression started, first biting, then flogging shoes. He was culled. Isaac stayed and was the breeding rooster. You don't want to breed from human-aggressive males because that is most likely what you'll get in the sons. JMHO.
