I'm trying to be thrifty building my first chicken coop. My dimensions are going to be 8 ft long 6ft wide and 8 ft tall. The champagne on a PBR budget here. I really have no idea building costs or quality of building materials, so I need help...pleeeeease. I recently made a craigslist's purchase of vinyl siding to do the outside with ($50 delivered for about 350sq ft). It turns out that it's actually for soffits, but I think I can make it work. The same guy will sell me 18 - 2x4x8s and 20 - 3/8"x4'x4' OSB siding pieces for $40 delivered to my house. Can someone tell me if this is a good deal?? I know I will need more lumber, but it seems like a good deal to little ole novice me. I was thinking about using the OSB siding for the walls on the outside and then priming it before adding the siding. Would this work ok? Thoughts? Thanks in advance everyone!
