4 batches of this years chicks made a flock of 19 hens 2 roos and a guinnea hen. They are in an 8 x 16 shed with 1/2 roosting and 1/2 food water and supplies. They are all mature now an im getting 2 eggs a day. Cleaned the coop, checked the feed, they free range about 2 hrs a day and have a 10 x 30 covered run. Seem happy but no eggs. Ideas?
