We have a Chickshaw 2.0, which houses 55 birds, comfortably. We are in SW Washington, and expecting an unusual cold spell with lows in the mid 20's next week. The chickshaw design has quite a bit of hardware cloth exposure on the sides, as well as the entire bottom, and I am wondering if/how anyone has winterized their chickshaw for cold temps. I know they will keep each other warm at night, but wondering if they will all stay warm ENOUGH. Would it be wise to add clear plastic to the sides, or do anything else to give them more protection?
