What size coop do you have? When I first moved the chickens out to ours I thought I would use the shavings. I had 5 bales and only did the one side barely an inch deep. It didn't seem like enough, so then I started tossing in the straw and hay and mixed it up. Then, in the fall I added in some leaves, not many, and when I toss them in, I don't cover much, just throw in a few scoops to give them something new to dig through. The ladies don't seem to like to be outside when the temps get below 25 so I try to keep them busy.Pine flakes here are $4.99 a bale, (I start out with 2) the bale is compressed, it spreads out a lot, then as time goes along 1 add part to another, etc by spring I have 4 - 5 bales on the floor (Remember, they come compressed.) It works for me. We do have lots of leaves but I'm always afraid to save them for fear of mold. I do use them along in the fall until snow comes. This winter, we went a couple months of below freezing at nights and most days. (Just commenting what works for me)
Thanks again.
