Maybe this has been asked, but I didn't see it. When a rooster does his business with a hen, how long does his stuff last? How many eggs can get fertilized if the hen lays every day? I ask because our roo isn't a very busy boy, and when he is, he's very selective to a couple hens. He'll tag the others about once a week, but when I get a hen to go broody, I want eggs from each bird to be hatched.
