Hi peeps, I live in Anchorage, Alaska and the winter is coming (believe it or not!!). I have 8 hens in a 10 x 10 coop and I believe it is insulated. I've been reading a lot about getting good ventilation during the winter, and my coop doesn't have any ventilation, except windows. I'm trying to figure out how to build it, but don't know where to start? If you have ideas or a ventilation in your coop, please share with me, and post some pictures!! Thank you.
