Welcome to BYC! Glad you decided to join our flock. You have a beautiful flock. X2 on what Mountain Peeps said about 1 rooster for every 10 hens. The only really good reason to have a rooster in your flock is if you want fertilized eggs for hatching. Roosters will fight with each other, and an excess of them can be very hard on your hens physically; over-breeding them, injuring them with their beaks and spurs, and battering them. Please feel free to ask any other questions you may have. We are here to help in any way we can. Good luck with your flock.
