Glad this is being asked, because I'm still trying to figure out my coop bedding and I'm not sure I'm getting the sand idea, either, though it sounds like to pick out the poops might be easier than shavings? Not sure, as obviously, I'm not speaking from any sort of experience!
And with regard to the "deep" shavings method: am I correct in that you just stir it around and occasionally add more to freshen it, but don't actually remove the waste for several weeks -- at which time you remove everything? This seems almost too good to be true.
Marquisella, you mentioned thick floor mats, which reminded me of a suggestion I was considering to line our wooden coop floors with linoleum prior to adding the bedding of choice. The linoleum is supposed to make clean up, especially annual or bi-annual scrub downs, much easier and it doesn't absorb the moisture and hold it like wood. I even saw a coop design that had the linoleum wrapped part way up the coop walls, kind of like you'd do a splatter guard in your kitchen. Our coop will be built a bit off the ground, on account of elevation/slope issues, so our floors will be wood. I was wondering about the linoleum suggestion....
