Are they getting 12 to 14 hours of light. My hens stop laying within 1 or two weeks of the days shortening If we do not put the lights on in the coop. I have a winter coop and a summer coop(Summer Coop is closer to field with no electricity for free ranging they love the ticks/ Winter coop close to house with electrity and more space for the winter months). ???? My new girls are not laying yet but they will in time the older girls are on there way out. Make shore they have 12 hours of brite light daily.
