I use shavings for litter on the floor. My floor is dirt. I have had chickens since June and I haven't had to clean it yet, thanks to my fantastic POOP TRAY!
Poop tray:
[You must be registered and logged in to see this image.]Basically, it's also a giant sandbox, only it's above the ground (giving the chickens more clean floor space to run around), and instead of shavings or sand, mine is filled with a product called Stall Dry. It draws the moisture out of the chicken poop and dries them up, so there's no ammonia smell in the air in my coop. I scoop the poop up as needed with a kitty litter scoop - once a week or so.
It's actually a little dry in my coop, I may have to sprinkle water around on the floor to get it just right. Or put more chickens in there to poop on the floor. Heehee.
I use nipple waterers:

I sanitize feeders and waterers for each new hatch of chicks, but otherwise, no. I want my chickens to be able to withstand normal germs. If I had a sickness go through the coop, I would certainly sanitize the crap out of everything, though.
I have shavings in my nest boxes.
I have a no-pest strip hanging, and I treat the chickens with Eprinex (for worms) and Frontline (for creepy crawlies) once per season. New chickens are treated before they go into the general population.
For cleaning, I just sweep the dust off of the horizontal surfaces, and would use a shavings fork to pitch out the old bedding. I am wanting to build up to the deep litter method, though, so there is minimal pitching of old bedding. I need to add some peat moss and straw to the bedding, but am still working on other areas of the coop, so that can wait a bit. Need hubby to bring me the core of a straw bale when he starts bedding shelters.
