I have a 31 week old Welsummer rooster and a 31 week old Easter Egger who I have put together for breeding. How long before I have fertilized eggs to incubate? I've not seen any mating but we're not out there that much. Before I separated the roosters from the girls (about 4 weeks ago) there was lots of action... is that because the boys were competing? FYI, I have them in a 25x25 garden during the day and at dusk they are in a tractor/coop together until the next morning around 7 am. Thanks.
