Hi - it's been a year now since I built my first coop and have had my first flock. Since the beginning, I've used pine shavings (I buy them in a bale from Agway) on the floor and in the nest boxes. However, over the winter, the pine shavings on the floor seem to mat up real bad, despite me constantly turning it over with a shovel, and adding a fresh layer to the top. I'm thinking of trying straw, but I was just wondering what the pros and cons of straw over pine shavings are? Thanks!
