Only did little things today, mostly to make assembly as easy as possible. I cut the tar paper to length for the roof. I also went ahead and drilled the pilot holes for the roof plywood. That way i don't have to try to figure out exactly where the rafters are while i'm clinging precariously to the roof. I also made some supports that i'll add to the bottom of the coop base so that my siding sits flush with the base while i nail it in place.
