I would turn the LED light off during the day, and set the time to have it come on at about 3:30-4 am. That way your chickens get enough "light" to encourage laying. Aren't chickens fun??!
Thanks junebuggena. The small window on the side is only poultry netting, and the roof is not flush with the roof, so we're curious about ventilation for the winter. We have time to make adjustments.
Here are some pics of our coop. We live in Wyoming. We currently have 3 RIRs, 1 Auracauna, 2 Black Australorps, 9 Barred Rocks, and 2 Polish Crested Roos.
