We went from 56* to -6* in a matter of hours. (Wind chill in the -20s) No way my girls could handle that! I brought them into a spare bedroom in the house. Put up a huge tent, lined it with a tarp and dumped in pine bedding. Cracked the window a bit, and my girls sat out the storm at a perfect 42*. Clean up was easy each day, my house wasn't covered in dust from chickens, and whole tarp bundled up at the end and dumped in the run. I also hung a bird seed bell in there to keep them occupied. Was so easy I'm upset with myself for not thinking of doing it this way before!
