It's perfectly fine to raise ducklings in the winter as long as you can provide adequate warmth for them.
I would suggest waiting until they are 3/4 feathered. Move to a heated garage (50-60 degrees) and let them be there without a light for a few weeks. That will help their bodies adjust to cooler weather.
Then you can move them to a coop and shouldn't have issues. Make sure it's well bedded so they can nestle and get warm. But by that age they should be able to regulate their own body heat and stay warm without a light. But some people will put a light out there as it makes THEM feel better
I suggest a 60 watt bulb, not an actual heat bulb as it's a huge fire hazard.
Also, when raising inside be sure to supplement with greens as often as you can. I like to use the bird suet feeders and fill them with romaine and cabbage leaves. Gives them a good source of greenery plus it keeps them busy!
