I use a mix of bedding. I do DL in my coop, and only clean it once a year. When I built my coop, I did not put a floor in it. I remember hating cleaning the coop every spring with its wood floor when I was a kid, so I knew I didn't want to do that. So after reading a lot of older books on chicken coops, I decided on a dirt floor. I love it. I get shredded paper free from work, and straw free from my grain fields, so I mix both with pine shavings. I start out with 2 bags of pine shavings in the 12x12 area, put 2 big bags of paper on top of that, then maybe 1/2 to 3/4 of a bale of straw on top of it all. The girls love to dig through it to find left over grain in the straw. I toss a few hand fulls of scratch on the floor daily, and the girls keep the bedding well turned, and I add new bedding every few weeks as needed. When I cleaned the coop this fall, I could not tell what was old bedding and what was dirt it had composted so well. What I took out of the coop was put into the part of the garden that I will be planting next year and was tilled under.If I get a bit of a chicken smell when I open it up in the morning I just put down a little new shavings, but I have never had a poop smell.
