I am converting a shed that had no front on it but has a 4x4 wood frame. It seems that the easiest way to add a door for my coop purposes may be a sliding door (human door). It is going to be about 5.5 feet tall because the shed is a bit short. I just want a simple wood frame with hardware cloth for the door, I just have no idea where to start when it comes to making a sliding door or any functioning door for that matter. I have researched it online and have an idea, but would really appreciate some tips for a custom sliding human door for a chicken coop. Thanks!!
