Someone has offered to swap me a huge set of sliding glass doors for the door I'd been planning to use for the big coop I'm building. I have to make the decision within about an hour. Do you think it would work okay? Too hot? The doors would face east and be about 10 or 15 feet from our house. They would take up almost the entire length of one side of the coop. I have roll-down bamboo shades I can put in to help keep heat down in warm weather, & can install lots of window ventilation. And/or put a "porch awning" in front of the windows. I'd LOOOOOOOVE to have the mega-visibility so we could watch the chickens from inside our house! How in the world could I keep sawdust out of the tracks that the bottom of the glass door slides on?? I would nail a 1-foot board across the base of the door inside the coop to hold back sawdust, but I'm sure some sawdust would fly through the air or stick to shoes still & end up in the track.
