The yard is just grounds of the ranch, its a multi step process leaving the ranch, first inside then outside and MAYBE back to the wilds lol. Steve have you ever thought about building an outdoor enclosure area for them? My idea would be a frame with mesh around it, with holes to exit and enter at their will, a watering hole, or a big dish to soak in, and some hides maybe a few climbs, call it a shelter/safe haven. Maybe its a bad/dumb idea but i like the idea.
