Welcome to BYC. Glad you decided to our flock. At one time or another, I've had all of those breeds over the years, and you have some excellent layers. Black Australorps are my favorite standard breed. They are extremely hardy, calm and gentle (my children, and now my granddaughter, made lap pets of them), and excellent layers of large, brown eggs. 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.Thankyou! Yes i have 2 barred rocks, 2 rir , 4 americanas, 2 black austolops and brown leghorn! How many do you have?
