I have a flock of chickens with 28 hens and 3 rosters. This summer i expand my chicken coop and the second day they where moved in egg production stopped i have made the 3 different types of nesting boxes, changed there food and water dish. They have hay in there nesting poxes and i give them high protein food as well as the regular laying pellets. I am lucky is i get 4 eggs a day when i use to get a dozen and a half... My hens aren't more than 3 years old and im clueless on what to do next?
