I live in Nova Scotia and it gets very cold well below 0 here (-35 with the wind chill a lot of times). Do I need to insulate the coop to keep the chickens alive? and what about frostbite? I have read to keep things dry and ventilated, but is that enough? Also can anyone recommend a water heater to use in the outdoor run? I was thinking of wrapping the outside of the run in plastic for winter months to keep the wind down and leaving the water and food outside so the coop doesn't get wet or a mess of feed. Is that a good idea or should I put it inside the coop for the winter? at night they will be locked up. I'm all new to this and I am getting cute little silkies so I don't want my baby's to freeze! I want to make sure before we start the reno to our shed.
