I'm not a fan of deep litter, or deep bedding. Ideally there should be no need for bedding on the coop floor. The chickens should be roosting on perches so bedding would seem unecessary except in the nest boxes. Currently I have a few that do sleep on the coop floor and I provided a thin layer of bedding for comfort.
The deep bedding idea is reliant on the bedding staying dry. Ime this is almost impossible if the chickens are exposed to the weather. They get wet and this sometimes provides enough moisture in a coop to make the bedding damp.
One of the most helpful indicators of a flocks health is in the poop. I clean daily, mainly so I get to look at the poop daily. With a small coop this isn't really a major chore if one is organized.
The deep bedding idea becomes a major problem in the event of a parasite problem, particularly worms. The chickens dig through the bedding and peck at it and the worm cycle just rolls on. It's also not that great for ensuring that the coop is mite free either.
There is also the matter of population density in the coop. A large coop with the recommended 4 square foot per bird may work better, but for many who have coops as roosting and egg laying only (the chickens are out in a run or free ranging during the day) some judge required coop space by room on the perch rather than room in the coop. I've always been a room on the perch style keeper because the chickens I've looked after leave the coop in the mornings and don't return until dusk, amoung other reasons.
It takes me a few minutes to clean the small roosting only coops I've used over the years. Chickens like clean.
