I am new to chickens and hatched my first batch
In your case it might be best to rehome or eat all of the cockerels until you gain some chicken experience.I have a young son and have kids around so aggression won’t fly.
With a young son and lots of children around displaying their natural behaviour (running, screaming, kicking balls, beating the ground with sticks etc.), I would consider it a safety hazard to keep the cockerels/roosters around, as any of these behaviours can trigger an attack that might cause severe damage to a child (eyes!).
