Bales of pine flakes, not shavings is what I use to avoid dust from the finely ground wood on the shavings. And it’s essy to sift through. I get mine at TSC. it’s the white shavings bag and says flakes right on it. Under $5 for 2 cubic feet.Are you talking the "bales" of pine shavings or something bigger? I currently buy the bales of pine shavings for my coop...I might try the pine shavings in the duck house. Thanks.
