I have a timer going. Its getting to where they are going to bed at like 6 pm...which its totally not dark out but its dark enough in the coop that I think its affecting production some. I have various stages of molters as well, which doesnt help. the timer comes on at 4 am. I was getting 10 eggs per day for a good 2 weeks..out of 20 hens. Now it ranges from 6-9.
