This is the scoop I bought to reach all the way to the back with my pdz setup. Sometimes you have to scoop the same spot multiple times but for the most part the small poops get sifted out.

I used to scoop it first thing in the morning when I let the girls out. But I figured out that if I let the poop sit till my afternoon chicken check, the nasty wet cecal poops are dried out and the sweet pdz granules behave like clumping cat litter. It also helps soak up any messes left on the perches so that you can scrape it off more easily later.
The coop stays so dry in wet weather and the girls like to hang out in there for their afternoon siesta even in the heat. My only qualm with it is that it's a bit dusty when being scooped. If you have an elevated coop like mine you have to really seal any gaps in the floor or close to the bottom or it will just trickle outside onto the ground.
