Siding
Anything I build gets vinyl siding on it. Despite the implications if the building catches fire (hint: vinyl is made from oil and burns really quick), vinyl siding is REALLY easy to put up, looks good, and is maintenance free. You can cut it with some tin snips (or a miter saw with the blade on backwards if you want to be fancy), and it goes up with a hammer and some galvanized roofing nails. It covers up imperfections and is easy to work with. I had vinyl on hand of mixed colors that went on the back side, and I purchased a carton that finished it off.
On the gables my original plan was to use wooden planks that I harvested from pallets to use as "siding" that I could ventilate by not letting them sit directly on one another. This proved very time consuming and wasn't worth the effort given the ridge vent, open eaves, and the loft door that would allow free flow of air through the coop. And needless to say, the vinyl looked like a million bucks compared to what I was trying to do with the pallet wood.
