I have an oddly specific questions lol. I live in Alaska. It is still light out when I go to bed around 10pm and already light when I get up around 5:30am. Right now, there's a brief period of true darkness in the middle of the night, but in a few weeks that'll be gone and all we'll get is dim. So here's my question- my coop has 2 low windows. Should I hang curtains so it's dark in the coop at night?
