I not sure what you're asking. Hens don't need to mate in order to go broody. Broodiness is a hormone thing that doesn't require a rooster to trigger it. If there is a rooster and he mated with the hens, that doesn't mean any of the hens will automatically go broody. Chances are, they won't. Heritage breeds (bred according to the breed standard) have a better chance of going broody than production birds. Birds, even of Heritage breeds, that have been bred for increased egg production are less likely to go broody.
