I'm a "they"?I light my coop in the evening to boost egg production. "they say" it should be done before dawn to prevent the bed time surprise of sudden lights out. But, my girls are fast learners. They're always on the roost before lights out. I prefer not to have my roo crowing at 2:30 AM, which would be happening if I had light only in the morning. After the time change, I'll have lights on at 6:30 AM - 10:00AM, and then on again 3:30 PM - 8:30 PM for the 14 hours that they need.
Any windows in that coop? If not, I recommend that you cut in some windows, and be sure they are secured with 1/2" hardware cloth for predator security.
Jack, I LOVE, LOVE, LOVE your coop.
