The most important thing with a young cockerel just coming into his hormones is respect, but it's a mutual respect between you and him that's crucial.
My latest roo is a nine-month old Cream Legbar. He was the cuddliest of chicks, loving to be stroked and he would fall asleep in my hands. When he came to the point where his hormones began to be evident, he began to avoid me. In fact, this is precisely what a good roo should do. At that point on, I refrained from handling him except only rarely and when absolutely necessary. He continues to do the "opposite poles magnetic reaction" when I am approaching him, neatly side-stepping to get out of my way.
If your young cockerel isn't doing this naturally, then you need to teach him to do so. If he dances up to you aggressively, or refuses to get out of your way when you're walking in his vicinity, you need to urge him to do so by "walking through" him. If he's outright aggressive, you need to run him off a good ways until he gets the message. If he attacks and tries to flog you, you must grab him up into a football hold and not release him until he surrenders and is docile.
Sometimes aggressiveness is a result of breeding, but a lot of time it's because a cockerel is insecure and doesn't trust his human. That's due to the human being unsure of themselves around the roo. Like dogs, roosters are quick to pick up on vibes we send out, even unconscious ones.
So, if your roo is avoiding you, respect that. It's exactly what he should be doing.
