i have two approx 24 week pullets..a barred rock and a new hampshire red housed with 4 younger girls about 14 weeks. the big girls ate getting heavier and red faces so i think ready to lay soon. all if a sudden they are all lurking around inside the coop in beautiful weather instead of being in run. what do people think?? olders thinking of laying and youngers just following?? its odd how much time they r suddenly insu ide!
