Spring has hit Adelaide with a bang and it's been hot and dry. I've been meaning to insulate the roof of Penguin's coop for a while now, but have only been motivated by the sight of hot chickens with their wings out. The roof in Penguin's coop is made of sheet metal, meaning that when the sun hits it, and the sun shines on it during the hottest part of the day, the roof becomes so hot that you can't touch it. The result is that the coop heats up like an oven, making the ground hot, which retains the heat into the night. My plan was to place a barrier to prevent this radiant heat entering the coop, making it more enjoyable for the chickens, not just during the day, but also at night.
