I have 9 girls, all bought the same day as 1-2 day old chicks. 6 BO, 1 RIR & 2 EE's. They free range, get treats and layer feed almost daily. At 21 weeks I received my first egg from one of my EE's. Now three weeks later, nothing from anyone else! Is this normal? When Miss EE's gets in the box to lay, the rest look at her like she's crazy. She lays nearly everyday. I see the signs, but I see no eggs. Any thoughts?
