I'm new to the chicken world. We have two back yard chickens. One is a Americana and the other is a Brahma. Our Americana has been laying a egg every other day. Why our Brahma hasn't laid and egg now for 7 months. Both chickens are young. They will be 2 in the fall. We have done everything to get the Brahma to laid extra oyster, good feed, and even taken her to the vet and she is in good health. I just don't understand why she not laying eggs. Do they have a cycle? We live in AZ so I don't think we get to cold. Can understand why she doesn't lay in Aug. and Sept just to hot. But to go this long with out an egg is puzzling. Can any one tell me why she is not laying eggs, I don't know what to do. Thanks.
