We do a little of both. I wish we could free-range our girls all day, but we have wild dogs in the neighborhood, and who knows what else would be interested in them during the day. Definitely hawks.
We have a covered run and a run that is somewhat covered that I plan to get some shade cloths installed. The semi-shaded run has a couple of grazing boards. The girls don't seem that interested in the few pieces of fodder that are poking through. I feel like I'm the most excited about those haha!
After work and during the weekends when we're home, the girls get to free range. They used to be confined to a temporary fenced-in area, but now they get to beebop around our property (almost an acre). We are constantly checking on them, mostly to make sure they're not going into our neighbors' yards, but also to have our presence outside. We have outside cats, so I'm not sure if that keeps curious beings away during those times, but we've been lucky!
