Tonight's low is 15 F with like 20 mph wind. My coop has no insulation and it has pretty good size air ways to ventilate. I can feel just a little wind getting inside. Will my chickens be okay? It's suppossed to be 15 F for the next 2 nights. Here are some pictures of the air ways. And coop.
Here I put a rolled tarp and a board to help stop some wind.
Also will they be okay during the day tomorrow with an open aired coop like this? Will they know to go inside if they get too cold?
