For the pee guy— a layer of pelleted bedding in the middle might act like a “litter box” and keep him drier.
For the churn and burn boy? Ugh. I’ve got one (a mare actually) and even having 24/7 access to her paddock doesn’t help, she goes in and out and pulverizes the poop. Inside? She just moves around and grinds everything to a fine mess. She lies down a fair bit, isn’t overly restless just has big feet and likes to move them I guess.
Some horses are just tidy. Some are pig pens. I far prefer pelleted bedding, about 4” deep, centered in the stall, some wetted into sawdust the rest still solid. I sweep my bedding back from the front of the stall where hay is fed, allowing them to move bedding only in the back 3/4 of the stall.
