Had a question, we have 3 hens roughly 3 years old.. they produced very well until February this year... one went through a hard molt and one a simple molt.. My daughter added to the flock in April with 4 more chicks and surprising one roo... now my older 3 are not laying eggs... all are free roam in the back yard, fresh water, fresh food, shelter (1 coop...I know we need to add one)... just don't know why there are no eggs anymore.. last egg we got was I want to say in June.
