Welcome to BYC. Glad you decided to join our flock. Golden Comet is one of many labels under which some hatcheries market their Red Sex Links (Red Star, as NorthFlChick mentioned, is another), and like all Red Sex Links, they are egg laying machines. It's great that you have a dog that doesn't chase your chickens, but do keep a close eye on him when they're together. As many BYC members can attest (often to their sorrow), dogs and chickens typically do not mix well, and even dogs who have shown no previous inclination to chase the chickens, suddenly and unexpectedly decide to chase and even kill the chickens. Once a dog has done this, it's almost impossible for to break it from doing it again. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your Golden Comets.
