We are getting ready to put up our hardware cloth around the run. We will also have a skirt around it. Is it necessary to also bury the hardware cloth, even though there will be a skirt? We have the 2 ft. high 1/2" 19 gauge, 120 lb. weight capacity, and we are planning on running stakes through it and into the ground. But is just a few inches deep okay? (Should have gotten the 3 ft. high stuff, but wasn't thinking).The stakes will go deeper, but I'm talking about just the hardware cloth. We will be using 1 inch wire for the skirt, out 3 ft. and will cover it with a few inches of our desert sand, and put concrete blocks on the top of it. Is this sufficient protection from digging predators?
