In the winter months, hens often take a break laying eggs. If you want them to lay through the winter, you can put a light in the coop and make sure they get at least 14 hours of light per day.
This is the time of year when egg laying slows down due to cold, shorter days and the birds recovering from the molt. Even though their feathers may be all grown in, it still takes a few weeks. Putting a light on a timer to give 14-15 hours will help. I give an hour before sunrise and a few hours after, so they can see to eat first and last thing. By January, your mom will see a sharp increase in eggs. The days are getting longer, and the molt recovery is over by then.
