We added a light to our coop and put it on a timer. It comes on at 3am and goes off at dawn then comes back on at dusk and stays on til 10. We started this about a week ago. We are still getting only 1-2 eggs a day from our 12 girls. During spring-fall we get 8-12 eggs a day. Nearly all of them just finished a molt. They are between 9 months to 18 months old. Does it take a while for the light to work?
