The most problems with males have been when we first got chickens-they were all the same age. Hormonal males, not yet laying girls was a real headache. Once you have a mixed age flock, and raise up a male or two in the flock, it should go much better. The older hens teach the younger ones how to behave. You may get an aggressive rooster still, but usually they are better behaved within the flock.
Since you free range, you’ll likely lose some chickens anyway due to predation. My neighbor (old guy) decided he was done with his chickens, so he took them to a relative’s 15+ acres, with permission, and released them. Yes, predators eventually took them, but they saw them for awhile, and the rooster for months Not my style, but that’s how he got rid of them. For us, we sell unwanted chickens at a livestock auction.
