Hello, I am building our first chicken coop and the plans have me burying the hardware cloth 1' deep. I searched the predator/pest forum and find the recommendations range from about 1' to 1 1/2 feet. I only want to dig once, and more importantly I don't want our chickens getting killed so I am wondering if anybody has had experience w/a predator digging deeper than 1 foot to get to chickens? My tendency is to go 1 1/2 feet deep for "insurance" but if it isn't necessary then I could probably find something better to do w/my time/energy than digging a trench. Known predators in our immediate area coyote, raccoon, skunk, and fox. I don't think they are "diggers" but there are bobcat and probably the occasional mountain lion coming through. Many thanks in advance for any feedback.
