I too need a screen door on my coops but I am getting resistance from the male in the house to get said task done. I worry dogs, coyotes or big coon could push store bought one apart. So I am going to get a good look at what is stock screen door then probably got grab 2x4s, corner brackets and some big freaking hinges. I have two rolls of 1x2 spaced welded wire here waiting the run installation so yeah door material.
