Welcome to BYC, Sarah. Glad you decided join our flock. Which part of Texas are you from? My wife and I were both raised in the great state of Texas. I have all three of your breeds in my flock, and you have a great mix of breeds. Black Australorps are my favorite standard breed. I've raised them for years (along with dozens of other breeds), and they are extremely hardy, calm and gentle (my children and granddaughter made lap pets of them and our Orpingtons as well), and the best layers of the standard, brown egg laying 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 chicks.
