It depends. In my experience, raising cockerels with same-age pullets CAN make it more difficult to have a decent relationship with them as they don’t learn things from their older flock members like they would in a normal social structure. Plus, children have no idea how to interact with roosters, which can set off a less tolerant rooster even if he interacts well with you. I had a rooster that was an absolute angel with me and every other adult, but young kids that didn’t know how to regulate their attention got spurred. I have also had roosters that were completely fine with even the most annoying kids.
Even if you supervise your kid, accidents happen, and you don’t want one slip to result in an ER visit. Personally, I would not recommend keeping the roosters in your situation, but that’s a generalization based on my experience with same-age flocks and how a good chunk of roosters react to that dynamic. Usually aggression doesn’t crop up until 8-12 months old so I would say wait and send them to freezer camp - no need to waste their meat.
