So I have some chickens that I hatched on Thanksgiving. They are close to reaching the 5 month mark to begin laying eggs. Recently I've noticed the rooster is starting to mount the hens and a couple of the hens are being very receptive to it while others just run off. I wasn't sure if those chickens who are receptive will lay first or if they might start laying earlier than the others? I figure they are obviously reaching sexual maturity, but I wasn't sure if it was a sign of eggs soon to come or not. Thanks!!
