I am in planning stages right now for my coop. I have some pressure treated wood from an old kick board that I could recycle. I know it's going to add unnecessary weight to my hopefully "mobile" coop, but I'd really like to reuse it. Is it safe to use treated wood on the coop? Also curious whether I have to paint the inside. I wasn't really planning on it. I'm in Vermont so keeping it draft free is my # 1 concern. Thanks for any tips! Below is my ideal coop style.
