We have some 6 and 1/2 month old BCM bullets who have not started laying yet. We live in North Texas, just south of Dallas. So it's still warm during the day and cool at night. But of course our days are shortening. It's light from about 7:15 to about 6:45 right now. Do you think these young girls will wait until spring to start laying! We've had them since they were babies and can't wait to see how dark their eggs are!
