Think DRY not warm. Dry and basic wind protection is what you need. Good ventilation is very important. Took me years to get this concept. The problem with heat, is to trap the heat, we close up the coop...what we trap is moisture.
Turn off the lights, and open the vents, they will be fine. I am in SD, and we get down to -33 degrees.
