Lazy gardener, you will be interested in this thread. I linked you to a page where I posted a lot of photos, but you may want to read the whole thing and see other people's ideas.
Our hoop coop is very large (20x24) and quite heavy, but DH has a tractor that we use to move it. The thing I like most about it is that one whole side is clear corrugated. It gets a lot of solar gain and is very bright. In the summer, we turn the clear side west or east, to provide shade so it stays cool. We also insulated under the corrugated steel that is on the opposing side, so it doesn't heat up like a tin can. And the chickens love the access to greens.
We do let them out to roam around, partly because the two roosters get along best when they can get out away from each other, although they've been locked up a lot this winter.

We have an electric fence that we connected to the run on our other coop, but we never electrify it because we don't have such a manicured lawn, and we run the fence through brambles and such. For the hoop coop, I just put up step in poles with snow fence. Ugly, but it kept them contained.
Next spring, I'm going to let the flock of older girls free-range, since we plan to send them to the freezer in the fall anyway. If we don't start losing them to predators, I'll probably let all the flocks take turns free-ranging, as long as the neighbor's dog isn't around. They've been free-ranging on warmer days this winter, but it is very limited territory, as they won't go in deep snow.
