I have one smaller coop and run totally enclosed with cattle panels, and one big coop 12'*10'+5'*5' attached to a 200' perimeter electric poultry netting run. All the chickens are currently in the large coop and run. I would assume it takes a few weeks to clear any residual semen from the female before I can set the eggs. I'd probably use the small coop as a honeymoon suite so to speak. I've not had any trouble with the males fighting. I'll eat any males that are not useful for crosses. The only male I wanted was the BCM. He is from a breeder. The Easter egger was a coin toss and the white one was supposed to be a girl.
