I too let mine free-range totally free. Oddly they don't seem to go in the veg patch nor in the polytunnel much even though the gate/doors are always left open these days. They seem to hang about with the geese in the orchard, or scratch about on the drive. Hope it stays this way.
I have loads of ornamental plants that I brought over with us from Scotland (always heve been a keen gardener but only recently became aware of
permaculture and self-sufficiency, now that we have a decent amount of
land) and i'd like to plant them out but i have to plan carefully as i'd be gutted if the chooks ate them.
