I'm trying to do a few things to get the chickens ready for winter. The hoop coop will have plastic on the ends in the winter, but right now the ends are wide open (covered in hardware cloth). The hoop-shaped roof is corrugated metal on one side, and corrugated clear on the other. When DH built it, he had started to line the metal part with a silver bubble-wrap-type insulation, but never finished. We had a rooster with frostbite, but otherwise everyone was fine.
We still have the roll of silver insulation, so I decided I would try to finish lining the ceiling last weekend. I did not finish. This morning I looked out and things were quite frosty, but the roof of the hoop coop looked like patchwork. Every where there was insulation was covered in frost, and everywhere else, the heat from the chickens had melted the frost away. I was pretty surprised by this. The ceilings are 10 feet high and the ends are open to the air, but apparently the chickens give off quite a bit of heat! I was thinking putting up the insulation was pointless, since the other side of the roof is just thin plastic, but now I am inspired to finish the job. I'm hoping the new rooster can get through the winter without frostbite.
Lazy gardener, I think you might need to change your name to hardworking gardener. Your chickens are lucky having someone dig up dandelions for the winter! I still haven't even dug my potatoes or carrots. The cooler weather that's coming ought to get me moving.
