This is a home made coop I've been working on for my three ladies. It's built around an old garden swing A-frame and has a ground level (half hardstanding, half earth) and an upstairs roosting area with 2 nesting boxes against that open hatch. I've painted primer onto the outside, but I'm not sure about how dark to make the upstairs roosting/nesting area? I've left a window space at the top on each side. My intention is to paint over the primer with dark green paint just from the upstairs level to the top of the coop so downstairs will still be quite light (they spend all day wandering around the garden area behind that wall, so they're rarely inside it during the day) How important is it that the upstairs be dark? Their old coop was inside an old guinea pig hutch which just had a tiny perspex square window near the top and a porch that kept the coop dark but accessible. So far they've spent 2 nights in this new coop but as soon as they're let out they run back to the old one to lay, and then stage a kind of sit-in protest by hanging around in it for half the day (very unusual for them!) Any advice much appreciated!
