Our flock consists of mostly bantams with a few light breeds, but we have multiple roosters and cockerels (don't ask me how many because I honestly haven't a clue - my bantam hens keep hiding nests and presenting me with more babies
).
We have much older ladies who keep the young ones in line, and everyone gets along. Some I haven't introduced until 3 months old but we have more girls than they all need and they all free range on our farm (not that they stray far from their trees). Any boys that are too aggressive towards the hens are culled but I've never had any full on fights between the roosters and/or cockerels. They will spar to figure out who's boss, but once the order is established everyone just gets on with it.
I've never had a bantam rooster/cockerel be aggressive towards humans and our one light breed rooster is also trustworthy with our kids and with visitors. I love having multiple boys, so it's definitely worth trying.
