Hi, I want to start hatching my own chicks soon but I'm stuck on the rooster's part. When he mates with a hen, is the egg (whether it has a shell or not) immediately fertilized? Or do I have to wait until the egg that's done 'growing' and ready-to-lay comes out, and then then next will be fertilized? In other words, do I let the hen cycle an egg out and the next upcoming egg will be chick-worthy? Please help!!!
