Out here, (Wilderville area), we day-range, the foxes aren't even bothered by the dogs in the yard. Unless someones home to supervise they have their runs only, I'm usually home but if it's raining they choose to stay in the runs like today. We knew the predators were here and built accordingly, some far no losses in 5 years. We roof the runs and bury wire in trenches, more work but we don't have to sleep with one ear open for trouble. Can't bear or cougar proof them but thankfully they just pass through rather than stay.Hey, I'm in Grants Pass, too!
I raise mostly Belgian D'uccle banties with the same weather conditions and most fare just fine. My coop is covered on all sides by barn, wood and tarp for winter, with heat lamps for the young'uns. They also get to free range everyday. I had predator problems at first, like raccoons and hawks, but haven't lost any for the last year to any. (but the year is young...)
