Hi, I have 5 ameraucana hens- Amanda, Maddie, Debbie, Louie (As in Lois) and Domino. They are all 1.5 years old, and since it is winter, they have a heater and light. They moulted about 2 months ago. Still No Eggs! I have tried everything from oyster shell to egg shell, yogurt to cheese, but still, NO EGGS! I's sure they aren't eggbound, because I can always feel the egg, and the next day, it's gone, no lumps on their bodies or anything. They, like, just DISAPPEAR! Please Help me!
