We are building our first coop and run and are trying to find ways to cut costs. The run will be 12 ft long, 8 ft wide, and 7 ft tall. Would fencing with 2 in by 4 in holes work to fence the upper half and top of the run? We are planning on using 1/4 in hardware cloth for an apron and along the lower 3 or 4 feet. We get snakes, raccoons, and hawks for predators.
