That's not yet a rooster, that's a cockerel. It's not about size, it's about maturity. Until he matures enough he will not challenge your New Hampshire rooster and the hens may even beat him up.
I don't know how many hens and roosters you are eventually talking about. There is nothing magical about any hen to rooster ratio, but that does not mean that you don't have to pay attention. With multiple roosters it's fairly common for each to carve out its own territory away from the others and attract his own harem. If you don't have enough room for them to do that your risks go up. Having cockerels and pullets in the mix can raise the drama dramatically. I usually suggest you keep as few roosters as you can and still meet your goals. That's not because you are guaranteed problems with more roosters, just they problems are more likely.
I'm going to repeat myself for emphasis. There is a big difference in cockerel and pullets versus roosters and hens. With cockerels and pullets in the mix the drama usually skyrockets.
I don't recognize that as a breed, he is some kind of cross. He could be a red sex link male, he could be a cross between two different breeds or colors.
I assume when you say "putting yourself on top" you re talking about the pecking order. Even if you can pull that off, you will not be there all the time. Don't expect that to reduce mating craze and aggression.
I don't know your goals, why you might want to keep him, your set-up, or your management techniques. If you really want to keep him you can certainly try. But I'd have a plan B ready in case it doesn't work out.
