I don't use lights with my hens and though laying was light over the past few months will molting thrown in too, they are beginning to pick up in laying. I just feel lights keep them from having their natural down time over winter when they need to give their bodies a rest, Not saying using light is wrong for ya'll but I just prefer not to use them, but I also have some hens that don't lay anymore so egg laying although a great plus to having chickens isn't top priority with me, I just like their company.
