What would you say if I told you that you would never have to clean you coop again? Well, you don't!!
It's called the Deep Litter Method (DLM), and it's what I use! Here's the short of it: put down four to six inches of pine shavings, and about 10 lbs of AG lime per 100 sq feet of chicken coop. Stir it all up. Watch the litter, if it starts to get crusted or wet, put down more litter. If it gets stinky, more lime. Stir every few days. The litter will break down and become dirt, which you can use on your garden and such. Many farmers will never clean their coop, only remove old litter when it gets too tall.
For the long of it, here's the article:

I suggest reading it, it's wonderful. Now, there is controversy on whether or not to use lime. The article says to use hydrated lime, but it can be corrosive and hurt the chicken's feet. I don't reccomend hydrated lime, but I do recommend AG lime. The difference is, one is "food grade" the other isn't. The ag lime is organic and safe for chickens to walk on or injest. It should be gray and powdery in color, as compared to hydrated which is pure white. Have you ever seen big gray mounds of dust on a cornfield, before it's planted? That's ag lime. Some people say that ag lime will hurt the chicken's feet, and won't use it. When I first started the DLM in the brooder, I put down the fresh shavings and ag lime, but I couldn't find my rake. So, I just stirred it up barefoot. It didn't hurt me, and it still doesn't. People will also use DE (
Diatomaceous earth) or Stall Dry. I have never used either, and again people will say it is not safe for chickens. Read the articles, and make up your own mind about it.
