Welcome to BYC. Glad you decided to join our flock. You have a nice mix of breeds. Australorps are my favorite standard breed. I 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 excellent layers of large, brown eggs. Other than the male Red Sex Link, do you have any female Red Sex Links in your flock? Red Sex Link hens are laying machine which will give you loads 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.
