We got our first hens back in March. We have four Buff Orpingtons, two Australorps, and three Auracanas. They are 6 months old now and we haven't gotten a single egg from any of them. They have plenty of layer feed and fresh water every day. They have plenty of space in their coop and a fenced area where they can range but since its contained, I can know that they're not hiding eggs any where. There's no signs that they are eating them and they all appear healthy. We do not have a rooster. Does that make a difference? Am I missing something or should I just be more patient?
