I think there is a world of difference in roosters and the size of the set up. If you have 15 roosters, I am going to assume that you are not in a small back yard set up. I think the original poster might be.
Roosters take space. If you just have small set up, of less than a dozen hens. And this is your first time with chickens, I recommend an all hen flock.
To me, the op, sounds like a child, who may also have siblings. If all of them are sharing the backyard, a rooster can be a problem. It is one thing for an adult to take a flogging in a free range situation, and a child confined with an aggressive adult rooster in a small yard.
So to the op - Roosters are not like puppies and kittens, whereas if you are nice to them, they will be nice to you. Chickens, hens included, meet each bird with one above and one below in the pecking order. When you cuddle and preen your rooster, have it sit on your lap, to me, you are taking on the under-bird position. As the rooster grows into his own, he has no fear of you. In chicken speak, that means no respect for your space. Often times these spoiled darlings become the nightmare.
So I am with the hands off approach. He should respectfully give your space of 5-10 feet, giving way as you move. However, if he starts to glare at you, if he puffs up at you, if he starts to sneak around back of you, those are signs that many people new to chickens do not recognize.
If you were my child, I would not recommend you keep a rooster for a couple of years. Roosters have ruined the whole chicken experience for a lot of people.
