This is not gonna be popular but here goes. I believe that giving a hen light to get then to lay when their body is telling them to take a break is not in the best intrest of the birds. Nature gave them the winter shut down for a reason. I do not know what that reason is but who am I to mess with it. As long as my gals have proper food and water I let nature take care of the rest!! Go ahead and take your best shot lol This is just an opinion.
