Osb

Does anyone know if OSB3 is any good for poultry housing i.e floors & nest box partitions?

We used to call it Sterling Board (if it is the same stuff<g>). Should be OK, but if it is a floor and likely to get mucky, I would put a good coat of varnish on the upper side to give a really smooth finish so it is 'easy clean'.
We always used exterior grade plywood for moveable livestock housing, but Sterling Board worked OK for the other things we did with it about the place.
