Welcome to BYC. Glad you decided to join our flock. I've raised Rhode Island Reds in the past and you should be aware that while they are very hardy and excellent layers, they can occasionally be aggressive (particularly the roosters). Are you planning on breeding them? If so, I would advise keeping on one rooster and getting five more hens to go with him. The recommended ratio of roosters to hens is 1 rooster for every 10 hens as too many roosters will be very hard physically on your hens; over-breeding them, biting and plucking the feathers from their necks and backs, battering them, and potentially, seriously injuring them. With real gentle breeds, you might get by okay with a lesser ration than the 10 to 1, but with RIRs I would definitely stick to the recommended ratio. Also, if your rooster turns out to be aggressive, I would get another, more gentle one as you don't want to breed that kind of aggression into your flock. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your RIRs.
