I find that they 'rest' areas instinctively, I guess driven simply by supply or lack thereof of whatever they've been foraging in that area until it has chance to reproduce and become worth foraging again, and/or by seasonal availability of said forage species (animal or plant). So while they can and do range all over the property, and the lane for a little distance up and down, it's noticeable how some areas are being worked harder than others at any given time and that the worked areas get holidays from it too.
It's also noticeable that they never go into the field in front or the field at the side, while they have and a few still do sometimes wander into the nearest neighbours' gardens. They are highly territorial, in other words, and the territory is surprisingly small.
