Hatching
That sounds like a great suggestion for most too. Unfortunately, the reviews I've come across said it nearly cracks like glass in the cold. I love ND but boy we're sure limited here on options! LOLLots of people have recommended Blackjack 57. I have no experience with it, and don't know how expensive it is or how it stands up to very cold temps.
I have 4-6" of pine shavings over the floor in my coop too. Soft landing for when the chickens jump down off the roost.
By the way, @WBZ,
