I live in western washington state and we have major problems with possum, skunks, coyotes, racoon and even the occasional bear or bobcat. I'm not talking living in the country, I'm in the city limits with houses everywhere! I'm just now putting everything together to start my little backyard flock. I'm planning on using an electric fence, along with hardware cloth buried two feet out from the perimeter of the coop. Mostly to deter domestic dogs & cats, but also racoons and skunks. We also do get the occasional coyote wandering through the neighborhood too. Heck, my buddy is a Pierce County Sheriff deputy and lives close to downtown Gig Harbor and he had a cougar in his front yard a few years ago! Not sure if an electric fence would work on one of those? Nowadays electric fences are fairly inexpensive too. Even one of the solar powered, battery operated fences can be had for around $100 or so. And those are supposed to be good for up to 4 acres!
