So I'm in the design/building stage of my coop and run. Finishing the run first and then going to clean the stall out and put the coop together. (Wish we already had chickens to eat all the spiders in there...) The run is 24' X 24' and is aprox 5ft tall and butts up against the barn, I already have the three sides covered with chicken wire, since we had that in the shed. I am throwing around some ideas for the roof. The barn is situated so it gets good afternoon shade. a. 12' X 12' panels constructed out of 2X4's and supported by 4x4's and deck piers, covered in either chicken wire or 2X4" welded wire. So four panels will cover the entire run b. The same as above, but one section will be corrugated metal roofing to provide an area for shade in the part of the run where the door is and to stay dry during the 9 months of Oregon rain. I've never built a roof before and would like some input on the best method for constructing the metal part. It would be attached to the barn and then angled down from there. Thinking about adding a gutter at the bottom and funneling into a catchment, partly to prevent draining into the run.
