Wow, I can't believe the education I've received since joining the BYC community. In reading this post, I just had a lot of my questions answered about chickens mating. I don't have any hens old enough to lay, and I have some very young birds I've hatched that I'm looking at possibly having some breeding pairs and selling some eggs (Black Copper, Blue, and Splash Marans pairs). Thanks again for all the information you provide!!!
