It's good to mix the chips with other dry plant matter, like leaves, grass.
I was lucky to be able to pick up some aged tree trimmings this year,
a year or more old so a lot of it was partially broken down.
At the same time we had dry weather so all the leaf falls were good and dry.
So I put a layer of the tree trimmings down the a layer of dry leaves.
Let them mix that for a day or so, then more of same.
They love scratching around in there...and bugs will hide/live in there.
