Welcome to BYC. Glad you decided to our flock. I've raised Buff Orpingtons for years (along with dozens of other breeds), and they are a wonderful breed; hardy, calm and gentle (my children, and now my granddaughter, made lap pets of them), and good layers of large, brown eggs. Speckled Sussex have very similar qualities and I have seriously considered getting some more of them. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck in getting your chicks.
