Well in Oregon the OSB may not last as long as plywood but here it last longer then plywood. With the heat here plywood tends to delaminate much sooner.http://www.jimsalmon.com/homepage.cfm?goget=2459
Waferboard and the fact that most people do not know it falls apart when wet and sags over time when plywood is much better and not that much more.
If I were selling coops to someone in a trailer court I would expect waferboard. Maybe that is your clientel and if so I apologize. I thought this was a thread about terrible quality coops.
