I'm in Kentucky and we are about to drop into the negatives. I've covered the outside part of my ducks' pen in plastic and laid down a lot of dry straw. Right now I am letting them roam as normal because it isn't too cold yet. When the temperature starts to drop I will put them up in there coop. I don't have a heat source out there though. They have never experienced this kind of freezing temps. before. Anyone know how cold they can handle? A lot of our freezing temperatures will be do to wind chill and I helped lessen that by covering the wire with heavy plastic. I'm pretty worried about my babies 

Hens go broody when you don’t want them to… and won’t go broody when you do.
