You'll get a hundred different answers here. I also have pine shavings on the coop floor and a little thrown up on the poop boards. I use an old dust pan to pick up the majority of the poo off the boards. Then I pick the dirtiest spot in the coop, usually right in front of the pop door, to pick up some pine shavings to throw up on the poop board. I just kick some of the pine shavings in the spot that I removed them from. About once a week I'll add some pine shavings to the coop floor, just on an "as needed" basis. The coop floor stays relatively clean because I'm always rotating the worst of it out. I will let the shavings get low and in the another month go ahead and remove them, clean everything down, sprinkle some DE down and put fresh shavings down. I scrub their roosting bars and the ramp up to them several times a year. My nest boxes stay clean. I pick out any poo and throw fresh shavings in there when it gets kicked out. I enjoy being with my chickens so I don't mind the upkeep. It gives me a chance to observe them while I"m working. Really, it takes just a few minutes every morning to do this. I also keep my run raked so that it's not contributing to the mess. I don't have any smell in my coop and my eggs are clean except for an occasional dirty one.
