Hello, everyone! I am getting my first order of fluffies in mid-March, and because I ordered from Meyer, I had to order a few more than we want to keep. -- we intend to give away/sell the excess chicks. At what age is it obvious what breed each of them are? I ordered 2 Blue Ameraucanas, and I will keep both, then I also will have 3 Black Australorps 5 Blue Andalusians, and 5 White Rocks. Thank you in advance for any help!
