We also live in Western Washington. With the predators in this area, I would definitely recommend a skirting or put wire down in the ground (skirting is easier). Also with the hawks, owls, Bald Eagles, racoons, etc, we put a fenced roof on the run. (See picture below how we have the run). Run is 4 ft tall. Made 4x4x4 panels. Made a center riser and put a tarp over the top, chickens can't be seen from the air, protected from rain and what snow we get. Had coyotes and rats come up to coop and run, wasn't able to get in.
Hope this helps, good luck. Julie
