I would consider free ranging being out in an area unconstrained by fencing or, at least, by fencing enclosing an area larger than they'd generally be inclined to roam and/or large enough that they can't strip the vegetation back to bare dirt.
I don't do free-range, but I'm planning on using my electric net to rotate pens so that they can regularly have fresh ground to work over.
