I had one girl ( black sex-a-link) I couldn't get back into the coop for a week in January when it was below -20 something she was fine ( it was a dry cold ).
I don't think I'll bother with heating the coop anymore just the water. Lots of debate and thought on this in the " winters coming check list thread"
