I don't change food/water placement with cold weather. Even if it's cold out I make the chickens go into the run for their water (I have a heated waterer), and I always have food both in and out, so that doesn't change. However I do shovel out the run (multiple times a day if needed) to ensure they have easy access to the water and feed areas, and just to give them some space to move around in.
My one concession with feeding was stopping fermented feed for the week, as it was freezing solid in the bowls in under an hour.
