This is only my first year and our low so far was 13F. I don't heat. It's going to get a lot colder here, as low as -10 to -15F. My duck house is insulated in floor, walls, and roof, but has big HW cloth windows. I put a tarp over the north-facing window and slid styrofoam insulation into the lower 3/4 of that window to prevent direct wind. The east and south windows are open, but I cover loosely with a tarp when it gets really windy or very cold. The west window vents into the run/pen, which is roofed and has a tarp over the north and part of the west side and is completely open on the south side.
I use deep litter in the house and fluff the upper layers of straw daily to move wet poop down towards the bottom, adding more straw when needed. The composting adds a small amount of heat. I could rig an aluminum can passive solar heater if I thought we were going to have an extended sub-zero cold snap. I can also close more windows with insulation, but am aware of the need for good ventilation to keep frostbite from being an issue. There is no food or water inside the duck house to keep moisture lower.
