All of these suggestions are good ones. But may I give a gentle reminder that while you may get steady egg production during their first winter when they are still young, the following years you will most likely see a decrease in egg production in subsequent winters. Some even stop altogether during that time and resume in the spring. Folks can continue with solid egg production by putting lights on a timer in the coop so that the chickens get 14 hours of light a day, which seems to be optimum for egg laying. By watching your sunset and sunrise times, you can set the timer to go on in the morning a few hours before actual sunrise to simulate that length of day. Others set the timer to split those extra hours - before sunrise in the morning and after sunrise in the evening. My worry with that is that they might not be all settled in to roost as they would with the natural gradual sunset and be caught suddenly in the dark when the lights go off. It's the amount of time it is light that matters, not which end of the day it comes on.
I don't use supplemental lighting in winter, but that's my own choice. I figure Mother Nature set the cycles of their little chicken bodies to do certain things at certain times of the year, and somewhere in there she allowed for molting and a rest from laying. I still got eggs from my girls all winter, but certainly not the numbers I got during the other seasons. And that's just fine with me. You may see things differently and that's what's fine for you. I just didn't want you to get your heart set on a certain breed cranking out eggs constantly regardless of the time of year. No matter what their feathers look like on the outside, the egg assembly line is pretty much the same - some like Red Sex Links (which I am so glad I have) and Production Reds are bred to produce more, but also tend to lay for fewer years. So you choose what you want to have in your flock, decide if you want lights or not, and there's no right answer! Fortunately here on BYC the questions are never a test!
