OK, so I want my run to be like Fort Knox because I will not be locking my girls in at night. The coop will be connected to the run and the run dimensions will be 6' x 12' and 6' high. The roof will be clear polycarbonate panels. I am discouraged by the cost of the 2x2 hardware cloth so here's my question. Is it ok to use the hardware cloth for the apron and bottom half of the run and use another type of wire for the top half? I live in Seattle and the predators I am most concerned about are rats, raccoons, opossums, and hawks/eagles. Any advise is greatly appreciated.
