A major retail DIY store near our area has a 10'x10' wooden shed kit on sale for $650. Our original plan was to collect scraps and cull lumber this summer to build our own shed-style coop. Our problem is that we are having a hard time finding reliable sources of decent lumber. Is this a good deal on a shed even if we add in costs to add windows, doors, ventilation, etc? Thanks in advance for your input!
