Hello. I am working on my chicken coop. I am converting dog house (4'x3') up 30" on 4"x4" and 2"x4" frame work. I am adding 2'x4' addition to coop. The run has a taller area with a human sized door to make it 4'x8' total. I am using 1/2" 19 gauge hardware cloth for vents, window, and run, but 19 gauge seems kind of thin. I couldn't find a thicker gauge version locally so I added white, large whole pvc lattice to the run, but the hardware cloth in the window opening still makes me a bit uncomfortable to leave open unattended. I stappled it to the outside of the opening and secured 2"x4"'s over it for security and for the window framework. The coop and run sits on concrete blocks and I put the hardware cloth all along the bottom of the run, tucked under the blocks, then added several inches of sand. When I finish the coop I will add a hardware cloth apron around the perimeter of the run. My 4 wyandottes, 2 silver and 2 gold, will be 6 wks. old this Monday. The coop will be very close to, if not finished, this weekend. We once had a raccoon rip open a sheet metal vent on the roof and have her babies in our attic. If she could do that what could they do to this cloth? Am I being an over protective Mom here or should I be worried about raccoons ripping through that hardware cloth?
