My 17 birds free range around my rural property during the day. 2 roos and an LGD, plus I am outside most of the time working on stuff, a stay-at-homesteader. We have every predator that the Oregon woods can hold, but since we're way out in the woods, the wild critters pretty much do their things undistrurbed. Why crash a guarded chicken coop when there are fawns about. I have a coop and yard. Coop gets locked at night, yard is covered. I put them in the yard when I go to town. I also have low-key blinky lights and Spanish talk radio going near the coop. My Airstream home is 30 feet from the coop. No losses yet, but no one is immune. Free-ranging takes some thought and supervision, but it is so worth it for the birds. Mine are very healthy and seem quite happy too. If I could not free-range, I'd have a moveable day-run. M worst predator fear is loose dogs, tho they are VERy rare out here. The mountain lions eat them.
