We are no chicken breeders by any means! My bantam barred rock rooster was killed by a hawk, so we had the crazy idea of trying to hatch out some of his eggs. The only hen we think he successfully mated with, due to her smaller size is my rir hen. They are in the incubator now at day 14 and doing well. Would a potential chick have any disorders due to the size difference? This roosters sister laid large eggs for her small size and eventually died of a severe prolapse. I am now worried we may have created something unhealthy, assuming they make it too hatch. Also, what would a barred rock/rir look like?
