I live in the snowbelt. Got through last year's Winter just fine with no heating but am starting to get nervous about our impending cold and snow. I have two winter hardy hens. Their nestbox is enclosed and well insulated with straw. They snuggle in there when it gets too cold and I close the nestbox door on really cold nights. They stil seem to want to be active and outside. (here they are walking in a blizzard http://s297.photobucket.com/albums/mm217/Kanthaka/?action=view¤t=Chickensblizzrd.flv ) The coop is well ventilated. I don't have electricity in my backyard and can't provide a heatlamp. Any cold weather hints from those of you who don't heat your coops?
