Brown's Naturally Fresh! Pine Bird & Small Animal Bedding
Pine (as well as walnut) molds super easy to the point that it can cause aspergillus in birds. If you want to use a bedding use a paper product. This also isnt good for them to breathe in due to dust
I was looking for a softer wood bedding for my bird's nest box. It is smaller chips than what I had but it's still hard chips to line a nest box with.
