I have a design for my 30x14 foot run with a gambrell type roof, the sides are 4 ft high. the idea is to have the vertical 4ft covered with hardware cloth and have a 2 ft apron around the perimeter. To save on weight and money I thought to put chickenwire over top the gambrell roof, but I am not sure if raccoons, who could easily climb up on the roof, could tear this apart to get access. Should I put 1x3 welded wire on top? Here's a pic of the sketchup drawing that I made. The coop and run sit in a wooded area with branches hanging over the area. Critters can easily climb up and over and drop in. Would chickenwire hold up to that kind of abuse? My thinking was also maybe using the 1x3 welded wire since it doesn't matter if raccoons can stick their hands through it, if the chickens are on the ground they cannot reach them. Your advice would be appreciated.
