I have 20 hens, all just about a year old now. By the end of the fall, we were getting a good 16-18 eggs a day. It slowed down a bit when the days got shorter, but increased again when I added a light to their coop for some extra hours of "daylight." I've since taken the light out, and egg production has really dropped, down to less than 10 eggs a day now. They have 12 hours of natural sun light now, which I thought was enough. Do you think I should add back the light? How many hours of light do thy need? I was also thinking maybe they were starting to molt, but tonight reading some other threads, it seems that happens more in the winter months. There are more feathers in their coop than usual, and one has about half the feathers on her neck than she usually does. Advice? Ideas? Suggestions? Thanks in advance!!!
