Chickens are not like kittens and puppies, whereas you handle them a lot, and they love it and are life long friends. There are many theories on how to raise a rooster, but the longer I am in this game, the more I am confident that it is the luck of the draw. Some are wonderful, some are awful, some go from the darling to the nightmare in an instant.
I do know that todays behavior is no indicator of next weeks, next month or next year. They are largely controlled by hormones and genetics. Handling them often often makes them appear friendly, but what really happens is they loose respect for you. Respect and fear are closely related in the chicken society. IMO you want a bird to naturally move away from you, not in a panic, just giving you the space equating with respect.
What you really need is a plan, not a wish or a hope that they will just be nice. Maybe you won't have to use the plan, but you need one. Make a decision how you will cull the bird if needed. Have a dog crate at hand, to put the bird in if needed. A long handle fish net can catch an aggressive bird, or you can pull him off the roost at night.
Most inexperienced people do not recognize the signs a bird is getting aggressive, until it attacks out of no where. People often times vastly underestimate the violence of an attack. They tend to attack children first, then women, then adults. You need to be very aware when around him. Children under 6, can take an attack in the face or head.
Your rooster is in the darling stage, enjoy that. He may stay that way, but there is a very good chance, at least 50% chance that he will not. Be aware and have a plan set up ready to go if he is not.
