Welcome to BYC. Glad you decided to join our flock. X2 on that 10 to 1 hen to rooster ratio. As they mature and their hormones kick in, too many roosters will become 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. The only reason you really need a rooster is to fertilize eggs for hatching and 1 rooster can easily handle 10-15 hens in that regard. Please feel free to ask any questions you may have. We are here to help in any way we can. Cheers.
