For any of the commercially available breeds, the normal breeding pattern for a hatchery flock is multiple roosters with a large number of hens. They must not kill each other or prevent mating, or that would not be the common practice. (That's where the commonly-quoted 1:10 ratio comes from. 10% roosters is typically enough to be sure all eggs are fertile.)
But that can be a very different situation than having a small number of roosters, and few hens, in a backyard coop.
In this case, yes I think most or all of the roosters should be removed from the females, for the sake of the hens' wellbeing. Butchering, rehoming, or another pen would all work as ways to remove them from the females.
