Most adult roosters are pretty tolerant of juvenile birds. Your young one won't start to act like a male for a few more months. Once he reaches maturity and starts trying to breed hens, your adult rooster may take notice of him and there may be some sparring for dominance. Or he may continue ignoring him. Or they will fight till one is seriously injured. It all depends on the temperaments of the males involved.
I have had many cockerels and adult roosters in my flock at once. Most will tolerate each other just fine, once the pecking order is established.

...any clue as to the color variation of this EE type? I know the lady I got them from sad they were a mistake in her order, extras, and she didn't know what they were. I'm assuming they are of a certain pure color...but what do I know??? LOL!
Yep. Definitely a cockerel. Hubby wants to cull him. I say he stays as a backup roo as long as he behaves himself & doesn't redirect my main roo's attention away from his various jobs. By the end of the year, I'll have 14 hens, so 2 roos isn't terrible, I suppose. I just hope Roo#2 behaves. Or he'll lose his head. Hubby is just looking for a reason...lol
