Welcome.
Ages ago when I was a kid, in addition to our flock or larger birds we had bantams mostly for my pets, cochins and probably mixed breeds. and we had both hens and roosters. If I remembered correctly, they seemed to pair off or each rooster had a hen or two or three. Sometimes the roosters would face off, but it never seemed to go further than that. Maybe because they free ranged on a lot of land, but they did go in their large coop, maybe 20 x 20, sort of a small barn, all together at night.
