RoboCoop Chicken Tractor Plans - Part 1 Here are the plans to build this: The sides, top, and back are 1/2" plywood. The frame is made with 2X2s (well 1.5"X1.5"). I used 2 foot wide galvanized hardware cloth for the sides. There is a 30 inch piano hinge on the back. This drawing was done with the free drawing program Xfig. Here is the fig file. I drew this up so that 1" in the xfig diagram is 1" in real life, so this drawing is to scale. The size of the xfig diagram is kind of insane, though, so set the zoom to .1.
