what kind of shavings

Cedar is an absolute no-no for chickens also.

Use pine shavings.

 

Yes use pine

 

I happen to have access to a hardwood sawmill and was wondering if the hardwood sawdust would be ok. The pine shavings I have been having to buy and I could get the hardwood sawdust for free.

 

Good that you are asking. Personally, I would never use anything small enough to be inhaled when they're kicking the stuff about. The big bags of pine shavings I get at the feed store go a long way and are inexpensive. I would also never expose them to treated pine in any form. Sometimes have to use treated pine around here for one thing or another and we cut the wood with a tarp beneath it and then vaccuum up the dust. It's not foolproof because the dust has a way of blowing about but I try to capture all I can!
