I was sitting here this afternoon trying to think how I want the coop to be. One thing that came to mind was windows. I have a bunch of old single pane ones from when we put new insulated windows in the house. I'm assuming it's ok to use those, but how many? Is there such a thing as too many? I love looking outside when I can't be there myself. Do chickens? I think I read something where light level and day length have something to do with productivity.... If that's true, I'd say lots of windows would be good? Thoughts....
