I finished my nest boxes yesterday and my wife ran to the store for me to get some straw. She came back with a bag of some sort of processed straw with no pieces longer than an inch. It was mostly dust. Anyway, I threw it in there.

For dinner - totally devoured twice their body weight in one morning
