Welcome to BYC. Glad you decided join our flock. I currently have Buff Orpingtons and Easter Eggers in my flock (and have had them both for many years), as well as Black Sex Links and Black Australorps, and they all do well together. Just be sure that they are not overcrowded as overcrowding can quickly lead to aggression, fights, biting and feather plucking, and even cannibalism with any breeds. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your flock.
