Ok... well, I was hoping to frame the coop with old barn lumber, because we have a lot of it, the thing is, it is apparently imported from the petrified forest. 2x4s are easier to work with and cheap.
Here's another thing, having a plan may make things go more smoothly and quickly, but it is not nearly as much fun. I envision this as a 4 day project. Tomorrow (or whenever the next nice day is) I'll hopefully get to the roof and siding. Bought some steel roof panels for that. Day 3 will deal with nest boxes, doors, and miscellaneous stuff, day 4 we paint.
