Did you build in other ventilation or is the window the only ventilation in the coop? If the window is the only ventilation, then you need to leave it open. They need some ventilation even in the winter. How much depends a lot of variables, so it's hard to say how much, unless we know more about your coop, like your location/weather and stocking levels. Cold won't hurt them, but a lack of ventilation will. It's not good for their respiratory systems and the excess humidity puts them at risk for frostbite. Ventilation can be as simple as an opening cut in the wall and a piece of 1/2" hardware cloth over it. We use screws and washers to attach ours, so they can't be pulled out of the wood. I like some ventilation that's open all year round and more that can be open in really hot weather.
The way I suggest providing ventilation pretty cheaply is like WoodlandWoman said, but make that hole higher than where they roost. You don't want a breeze blowing on them in the winter. If you have a couple of decent sized openings on different walls above them when they are sleeping, you are doing real well. Moist air can lead to frostbite, which is your enemy. Warm air rises and holds more moisture than cold air. I can't come up with anything bettter than openings above them.
