I live in PA, and we get some pretty cold winters. I have raised the typical Barred Rock, Australorp, Orpington, and do NOT recommend them. Yes, they will live through the winter, but they will not be comfortable. You need a bird with a small comb/wattles. Smaller combs/wattles means less heat loss through the head, as well less chances of frostbite.
The following egg layers are more suitable for cold winters.
Rosecomb Ancona, Ameraucanas, Buckeyes, Brahma, Chanteclers, Dominiques, Rosecomb Dorking, Easter Egger, Hamburg, Rosecomb Leghorn, Rosecomb Rhode Island Red, Wyandotte, and Russian Orloff.
