chickens in winter

Are weather says in a few days the night will get down to 1 degree F. Most of the are in larger groups of 20+. Can a group on bantams take that temp? We have standard sized chickens and bantams. Is there anything in particular I can do to help keep them warmer other than supplemental heat? Thx,
