Chickens went in the coop and run for the first time last night/this morning. They lasted 3 hours alone. Our jack russell ripped the hardware cloth and dug (we have it a foot or more down) and got in. Luckily we caught her herding them around. Do I need to do another layer? I've read over and over that hardware cloth is the best.. Anyone used an electric fence? Will this help? I really can not be out there watching her all day and night.
