Okay, it's been 6 weeks now without an egg! My adult RIR hens must be finished. They laid consistently, even in the winter. All I can figure is the stress of introducing the 12 barred rock 4H chicks was too much. They appear to be in great health, nice silky feathers, legs nice and yellow, beaks and eyes are clean and clear. Has anyone's barred rock 4H chicks laid yet?
