Mine is actually quite strange! Since the only thing we have to worry about is hawks (there is nothing to climb into the run during the day, that we know of!) we simply have neon twine stretched out across the run. This allows full sun and air in, but would stop any dive-bombing hawk, as its wings would get tangled in the twine. This also keeps my NHR hen from jumping up onto the fence or coop! We have not finished installing it completely.
EDIT:
Oh and my coop is a wooden one i designed and built. I painted it with white outdoor paint. to hopefully keep it pretty cool inside, since i live down in southern louisiana.
The roof on it is a sloped wooden one, and it lifts in two sections to allow for easy cleaning. I am adding on to the back of the coop, and that will have a similar lid that will open for easy cleaning and egg collecting.
