Well for an example, up here in Maine temps below zero are not uncommon in winter and I have never used supplementary heat. The birds do quite well.
I do use a 50 watt base heater under their water pan to keep their water from freezing but that has no effect on the temperature in the coop. It just allows them to have access to water and makes it easier for me when I change their water pan every morning.
The only thing I do different is to collect the eggs earlier in the day so that I can get them before they freeze.
