Welcome to BYC. Glad you decided to join our flock. It's always so exciting getting new chicks, even after having raised chickens for 50 years. All your breeds are friendly and docile. I've raised all of them (still have all of them except the Speckled Sussex). My children made lap pets of the Australorps, Orpingtons, and Sussex. The Black Australorps are my favorite, standard breed; extremely hardy, calm and gentle, and the best layers of the standard, brown egg laying breeds. Our Easter Eggers are my granddaughter's favorite chickens. She loves their colored eggs. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with the new chicks.
