I think what you're referring to is the "deep composting method" and I found that with eleven chickens, no amount of turning, new material, etc, could help keep the sheer volume of poop that accumulated dry.

We didn't have a name for it, but I did already state that it was not wet enough to actually rot in place.
In earlier years, we had 7 chickens in a 4x8 foot coop. They also stayed inside all winter. Their bedding was usually had either wet patches (summer) or frozen patches (winter). The bedding fell out the door when it got somewhat deep. The chickens did not keep the bedding stirred up well, either, and that coop got cleaned a lot more often.
Yup, we had a lot of that the first winter with the big coop. (My Dad thought chickens needed to be warm. We made changes before the next winter.)The concern with that much poop is the ammonia.
We did not turn in the poop; we dumped the kitchen scraps/compost in each day; weeks or months went by between times when we added fresh bedding, although then we did add several inches at a time. Very little labor. I remember a very few times grabbing a pitchfork to break up a mat of manure right under the perch--maybe a few times each year.Honestly it took me more time to turn the poop daily, go get the fresh bedding and add more to it every couple of days, and then to constantly be buying more bedding.
Our chickens were shut in all winter. They did a lot of scratching in the bedding, and even took dust baths in it. I think it was partly because there was little else to do, partly because that's where we dumped the food scraps, partly because they had more space--the ones in the smaller coop in earlier years did a lot less scratching. I think the chickens scratch because they're looking for stuff to eat, and with the mixture we had, they were forever picking out bits of stuff and eating them. (I do not know exactly WHAT they were eating, and I'm not sure I really want to know--but it certainly did not hurt them.)My chickens never scratched around in their bedding either. Even on the coldest most miserable of days they only come in the coop to lay eggs.
Glad you found what works well for you! I enjoyed your article--interesting to see what different methods are best for different people.Switching to Grounds coffee bedding (or sand) has made my daily cleanup a breeze.
My Mom did not buy bedding. We raked leaves under our own trees in the fall; a few times we hauled wood shavings from a sawmill; one year the utility company was chipping brush and dumped a big pile of chips for us; a few years when we thought we might run short of bedding we volunteered to help rake leaves off the lawn at a local church--then brought all the bagged leaves home with us. (Great for them and for us: they wanted the leaves gone, we wanted to have the leaves.) Now that I think about it, straw/hay were mostly not used, probably because of what things were available free for us.I'm spending way, way less money on bedding as well.
