Not exactly sure how to ask this, but let's see if I can make sense. When a roo mates a hen, how many fertile eggs will she get from him? Like if she was with him for a few days, then you took him out. Someone told me Finches could mate for a few days, then she could lay a bunch of fertile eggs even after you separate them. Has me wondering how it works with chickens, as I thought they needed to be mated for each egg... Thanks in advance!
