Your perspective changes when you muck yourself. Mine have been in for 2 days straight and the manure load triples compared to the stall cleaning when they are turned out 1/2 the day.
It's perfectly acceptable to only clean 1x/day. Horses that have their stalls cleaned that often try to keep them as clean as possible so that they have a dry, clean place to lay down. You don't have to strip the entire bedding every time. In fact, I only have to clean up the urine soaked bedding, and apple pick the manure, then a use a broom to push yesterday's bedding onto those spots, and add some new. They pick their spots and pee and poo in the same places. My three really need brushing, but my neighbors can see the one side of clean shavings sticking to their coats from the night before.
