Welcome to BYC. Glad you decided to our flock. Any breed of rooster will breed successfully with your hens, but I would suggest going with a breed that has a well deserved reputation for being calm and gentle (potential lap pets) such as Australorps, Orpingtons, Brahmas, Cochins, Sussex, or Faverolles. You don't want to breed aggression into your flock. If eggs are a primary consideration, I would get an Australorp rooster, as they are the best layers on this list and a Aussie roo will help breed that excellent laying ability into your chicks. Please feel free to ask any questions you may have. We are here to help in any way we can. Whatever breed of rooster you decide to get, good luck with your flock.
