As the other's have said, they do take longer to mature. Our girls took around seven - eight months to start laying. But, boy are they good layers. They are actually our best layers on the farm, and we usually get an egg a day from each of our hens.I WILL BE PICKING 8 ON SATURDAY MORNING A MIX OF 8 BLUE AND BLACK 10 WEEK OLD , ARE THEY GOOD LAYERS I KNOW THEY ARE VERY FRIENDLY AND CURIOUS BIRDS WOULD LIKE ANT FEED BACK ON THIS BREED .AS THEY ARE NEW TO ME THANKS
