Thank you for your reply. I'm still a bit confused about deep bedding and deep litter but this is helpful. But, please expand on the "giant slip and slide"! ;-)
In response to your request of explanation. Seems to come up every few years, LOL.
I've found deep bedding to mean using layers of bedding in the coop itself (or a chick brooder). It's usually done on a floored coop (doesn't go to the ground). It is kept dry. If water is spilled or rain/snow gets in, the wet bedding is removed. The bedding can be any type. As the bedding breaks down (even non-composting set up breaks down) due to chickens dust bathing & scratching around & their poops drying up, coop tender does 1 of 2 things. 1 - completely removing all bedding & sweeping or vacuuming up the "dust". This is done weekly, monthly or whenever it appears to be needed. OR 2 - they add more dry bedding to freshen the bedding, only cleaning out 1-2 times a year. The removed bedding then needs to be composted. Over the winter, directly in a garden bed or added to hot compost piles/bins.
Deep litter method (also known as DLM) is usually done where the litter/bedding comes into direct contact w/ the ground or natural soil. It is a form of constant composting that allows for removal of "finished product" that can go directly into the garden at anytime of the year. It is also done in a combination of ways. Some use wood chips or mulch. Can chip your own trees, get delivery direct from arborists or sign up for ChipDrop. Others use a combination of materials. Materials are all natural types that will break down or compost - wood chips, pine straw, pine shavings, hay, straw, hemp, rice hulls, corn stalks, lawn clippings, garden trimmings, shrubbery pruning, weeds, veggie scraps from house, coffee grounds, shredded paper products (junk mail minus plastic windows, paper, household boxes, cardboard, phone books, etc).
The main idea is that you want the materials to be different sizes &/or types. This allows water to percolate through as well as allowing aeration. Both of these mean that there won't be standing water as it absorbs into the litter "sponge" & the poop breaks down w/o smell or flies. If you have smell or mud or standing water, you would need/want to add more litter (natural materials listed above). You do need some damp or wet - to keep the litter breaking down or composting. In a dry region, this may mean watering the run (& coop) or at least dumping & cleaning waterers out there. In a wet region, this may mean adding lots of materials to become a good sponge or fully roofing the run to keep excess water out.
DLM can be done in a floored coop but can be more difficult to get started & to maintain. It can also cause damage to the coop. To get it started, you'll want to "inocculate" the bedding w/ soil from your garden, from under shrubbery or trees in a local forest area. This has local micro organisms & bugs & will start the composting of the DLM. Every time the coop is cleaned, it will need to be innoculated again. Since the DLM needs moisture, the litter material will need to be sprayed - completely opposite of a dry coop. A wooden floor & at least the lower walls of coop need to be protected from the moisture. Exterior paint, Black Jack 57 or some type of linoleum or waterproof flooring works.
There are several good articles throughout BYC. The reason they contradict each other is simply "different strokes for different folks". Also, different regions have different weather conditions, meaning what works in one area doesn't work so well in others.
I love DLM. Keeping material slightly damp during dryer spells means little/no dust or flying dander/feces. Not having to actually clean a coop - previously priceless due to our work schedules. Now that I'm not working & getting older, just nice not to have to deep clean.
A great video on DLM - done by a member of BYC.
