Hello All, I want to make a sliding door for my coop that slides up, because I will be building a short run soon, and a lockable door will no longer work, we would have to go inside the run (about 4" tall) to open and close a coop door. So Anyone have experience with sliding door? My thought was a 13x13 plywood held in place by 2x4s, with a metal rod and handle attached to the plywood, with a notch to hold the handle and thus the door open in place. This sound good? Anyone have ideas or pictures on what they did? Any problems with this set up?
