Hi, I am new to chickens. I got 9 chicks in April, all were supposed to be hens, but 5 were roosters. Found good homes for the roosters, and had 4 hens left, 3 Australorps and one California white. A week ago we got 2 Rhode Island Reds and 2 Ameraucanas. They are almost 2 months older than my other hens, the Rhode Island Reds are laying but the Ameraucanas are not. My australorps are picking on the ameraucanas pretty badly. Could that be why they are not laying? The australorps and the california white are not laying yet, I am hoping that by October they will be old enough and will start laying. Any advice would be great!
