My 4 Barred Rocks are going on 26 weeks old now. I got them all together at the same time, they are from the same shipment from the hatchery....so they're all the same age. 3 of them lay consistently, mostly every day.... and have been for about 4 weeks. The 4th hasn't laid an egg yet, nor is she showing any signs of laying (no squatting as the others do). And, no... she is not a he. Any words of wisdom from you veterans? This is my first flock, so wondering if this is a "normal" occurrence..... where some birds just take longer to mature. Thanks for the insights.
