God bless you for doing it first because that's what I want for my stock shed. We've heavy clay and low frost but I want a well insulated place for the actual livestock. And I don't want a ton of small buildings, apparent, on the property. I'm going to try for doing it with local cedar log rounds. I want the round log practice and it's cheaper. As it is the plans for the large turkey coop are being drawn - just don't tell Laura. I've a neighbor with some salvaged industrial belts - 4 ft high we'll be using for exterior to the logs, moisture prevention. It's about 1/4 inch thick, lovely stuff. Thanks for the pictures - keep us posted.
