Bedding has one job and it is not comfort. It is absorbing moisture fast enough that the coop never smells of ammonia, because ammonia is what damages birds.
Pine shavings are the default for good reasons: absorbent, cheap, compostable. If your coop is small, close to neighbors or poorly ventilated, a hay-and-straw blend with zeolite mixed in targets the ammonia specifically. Never cedar, whose aromatic oils are a respiratory irritant.
What bedding is actually for
It is easy to think of bedding as comfort. It is not. Chickens roost on a bar to sleep and they do not much care what is under them. Bedding exists to absorb droppings and moisture fast enough that the coop does not develop an ammonia problem.
Ammonia is the thing to actually worry about. It is produced as droppings break down, it damages the respiratory tract lining, and it makes birds more susceptible to everything else. The practical test is your nose at coop height on a still morning: if you can smell ammonia, the birds have been breathing it all night.
And ammonia is a ventilation problem as much as a bedding one. No bedding rescues a sealed coop. Ventilation versus draft is the companion page and arguably the more important of the two.

Nothing. Do not use it
Aromatic oils are a respiratory irritant
Koop Clean is the only bedding in this category we found that publishes a coverage figure at a stated depth — 63 square feet at 2 inches — which lets you actually work out how many bags a season takes instead of guessing. Small Pet Select is the only one publishing a dust figure. Everybody else publishes a bag and a photograph.
Deep litter, briefly
Deep litter is a method rather than a product: you add fresh bedding on top rather than stripping the coop, and the layer composts in place, generating a little warmth and a microbial population that competes with pathogens. It changes how often you do the full clean-out rather than removing it. Done properly it works well and reduces both labor and cost.
Done improperly it is a damp, ammoniac mess. The requirements are real: a dry coop, good ventilation, enough carbon material added regularly, and turning. If you are not going to commit to that, plain shavings changed regularly is the more reliable choice and there is no shame in it.
There is a published number behind all of that, and it is the whole difference between the two outcomes: the deep litter method page works through the litter-moisture threshold extension research puts the method on, and the routine that holds it.
Nest boxes are a different problem
Loose bedding in a nest box gets scratched into a corner within a day, and then eggs are landing on bare wood. That is a different requirement from coop floor bedding and it has a different answer — pads that stay put. Nest pads covers it.

What it gets right
A published dust figure, which almost no bedding brand states at all — and dust is the specific hazard in a small enclosed brooder
Volume published in liters expanded, so you can compare bags rather than guess from a picture
Pine shavings are the default bedding for good reasons: absorbent, cheap to replace, and they compost
No dyes or additives, which is what you want against a bird's respiratory tract
What it costs you
The 99 percent figure is the maker's own and comes with no published test method
Costs meaningfully more than a farm-store bale of shavings, for a difference you cannot see
No zeolite or odor control, so ammonia management is entirely down to your cleaning schedule
Skip it if. You are bedding a large, well-ventilated walk-in coop. Buy the cheap compressed bales and spend the difference on ventilation.
Pine shavings for most coops: absorbent, inexpensive and compostable. If your coop is small, poorly ventilated or close to neighbors, a hay-and-straw blend with zeolite mixed in targets ammonia specifically. Avoid cedar shavings entirely, because the aromatic oils are a respiratory irritant in an enclosed space.
+How deep should chicken coop bedding be?
Two to four inches for a conventional change-out approach, deeper if you are running deep litter. Koop Clean publishes coverage of 63 square feet at a depth of 2 inches, which is a useful figure for working out how many bags a coop takes per change rather than guessing.
+Is sand good bedding for a chicken coop?
It drains well and can be sifted daily like a litter box, which some keepers prefer. Against that: it is heavy, it does not compost, it gets cold in winter, and it is dusty when dry. It is a workable choice for somebody committed to daily sifting and a poor one for anybody who is not.
+Why does my chicken coop smell of ammonia?
Because moisture and droppings are accumulating faster than the bedding absorbs and the ventilation removes. It is usually a ventilation problem rather than a bedding one. Ammonia damages birds' respiratory tracts, so treat the smell at coop height on a still morning as a problem to fix rather than a normal condition.
