I would say if your roosters get along, keep the number of roosters you want, if they don't get a long, re-home or eat or just cull the one that doesn't get along. I recently had 4 roosters, they got along, and didn't attack me, but one I didn't like at all, so I culled him. not long after culling the one I didn't like, a hawk got one of the roosters I did like. So now I am down to 2, I keep the main rooster (BCM/Icebar/blue cochin bantam mix that is full size) I can pick him up. And an EE beta roo, that up until now didn't crow, but the both have crow collars on which doesn't prevent crowing but does cut noise in half and shortens the crow.
