I'm in Alberta..Same weather. I run heat although the water freezes. My Coops are cold but not close to the outside temps ..Best wishes fellow Canadian.I’m in ontario and we are in a polar vortex, have been for a week (minus 30 and minus 40 wind chill). I have 4 ducks and a couple of geese- 6 months old - they have shelter 8x 6 by 3 feet tall - not insulated - nor heated. I had been using woodships and layering the bedding - switched to hay for the weather this week - seems to be keeping them warmer. They get out to drink ( heated bucket) and eat. The pen is about 50x 50. But they aren’t walking more then 2 feet from the shelter... I’m a little worried - but so far so good. Thanks for the info.
