A very strong head roo can do a pretty good job of keeping younger cockerels in line and can even monitor overmating. But he can't be everywhere at once, and eventually, the hens will suffer with an imbalance of roos to hens.
I'm just as concerned about this cockerel being human aggressive. Six months is still just the very early weeks of his maturity. For the next six months, how he's handled and how his humans relate to him will have direct bearing on how manageable he will be when his hormones really start roiling.
Handling a cockerel "a lot" is usually a recipe for misunderstanding and misread cues. Better to ignore him as much as possible, intervening as necessary with discipline on the spot when he gets out of line.
Generally, you want to treat a cockerel as if he's invisible. His behavior shouldn't cause you to pay attention to him as long as he's behaving within his role as a rookie rooster. If he's standing in your path, you walk right over him, forcing him to remove himself, rather that walking around him. If he makes any aggressive moves, dancing, or pecking or coming at you, then restraint is called for until he submits.
It's very important to keep his role and yours separate. You are the flock manager and he is one of the flock protectors. If you interact with him too much, especially in emotional ways, he will get confusing signals, become stressed and unpredictable.
There are good roos and bad ones, usually starting out that way by temperament. But how we relate to a cockerel in his formative months determines very often what sort of rooster we will end up having, a well behaved roo or a demon.
