Posted in another thread but not much response. I was at Tractor Supply the other day and found bags of pine shavings that expanded to 2500 cu inches when opened. My coop is going to be 6 feet by 12 feet. Six inches of shavings would be (if my math is right): 6 feet = 72 inches 12 feet = 144 inches So, 72 X 144 X 6= 62,208 cubic inches! That's like 25 bags at $9 each or $225! And that's just for the initial application. Where do I get enough Pine Shavings for Deep Litter Method?
