I wanted to share my newest money saver. I am using cut up cardboard as coop bedding, doing it like a deep litter method. No dust, and it's all recycled. We have a couple stores around here that let you take the boxes with you when you get groceries, so we have been keeping a bunch and then cutting them into squares about 1 inch by 1 inch. It keeps the coop dry, the smell at bay, and it's free!
