Better take advantage of that quick like. Sawdust was cheap here, prefferd for dairy farmer's and we have lots of them. Not anymore they either chop grass for bedding or big farms now use sand... sawdust is non-existent , all sawmills make wood pellets now for home heating, big money. Used to be pretty much given away, now none.I can get a trailer full of sawdust for $3. Pine shavings are $5 a bale. ;-)
We use sawdust from cutting our own firewood, and dead dry tree leaves for our chicken deep litter bedding.
