Thanks for your correspondance. My light is inside the hen house, set to come on early, so as to extend the morning and set to go off around eight. But, the silly things wont roost inside, so the light is doing them no good. It's not a big issue with me, however, I only have four hens. I do think if it's cold enough, surely they will go inside the hen house to roost. Right now they are still making enough eggs for our family, so that is really fine with me. This has been a new experience for me this year, but so far, it has been a good one. I started with five gals but had to remove one because they decided they didn't like her. She is living with my goats now, and seems quite happy. She had a place all to herself, but elected to roost in with the goats which is kind of comical. I love the animal world.
