I got some FREE saw dust/chips for our coop today from a new cabinet shop that just opened. He said I can have all I want, it is in large contractor bags and each bag is a different kind of wood, NO CEDAR he does NOT use cedar. So what I am wondering if this stuff is going to be too fine for the coop or not?? My mom seems to think it will be. It is more of a 'dust' and he said it came from the plainer, but there are some larger shavings as well, but they are just kinda mixed in. Some bags have pine (only pine), some have oak (only oak), etc., etc., etc.. What do you think? Get the FREE stuff and use it in the coop (4ft x 6ft) or pay the $3.00 (Plus) from Tracktor Supply per bag every 3 to 4 months??? The bag that we get at TS covers the WHOLE coop and is about 4 inches deep.
