Now that lumber prices have gotten outright ridiculous... What non-wood materials has everyone used to build a coop? I was thinking of designing my next coop out of pvc, with 7 foot t-posts for stability, for the framing and hdpe sheets for the sides/roofing. That would probably be less than ideal but I just priced out how much it would be to build a 4x8 coop and wanted to throw up before I even got to adding in the roof.
