We have lost a couple hens to a raccoon, which tore through (what we now know is totally not secure) the plastic netting draped across the top of our run. I am looking for advice on what to cover the top with. Note: we are trying to raccoon-proof the run rather than their house within because we are not able to consistently get home by dusk to secure the house. The walls of the run are 8 ft tall with 1/2" hardware cloth along the bottom half and 2x4" welded wire on the top half. The run area is 8 ft x 16 ft, so that is the area we need to secure. Will 2x4" welded wire be strong enough for covering the top or do people think we need to go with hardware cloth? We are aiming to get this done tomorrow afternoon before we have another evening. Thanks.
