Coop bedding, judged on moisture and ammonia

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.

By Scooter M.·Published September 1, 2026

A pile of clean pine wood shavings

The short answer

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.

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. 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.

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 coverage figure at a stated depth, which lets you work out how many bags a season takes instead of guessing
  • The zeolite is mixed in rather than sold as a separate product you then have to remember to add
  • Ammonia is the thing that upsets neighbors and damages birds' airways, and this is the only bedding here formulated against it
  • Composts cleanly, which matters if the coop output is going on a vegetable bed

What it costs you

  • The maker does not publish a bag weight, dust level or absorbency figure, so it cannot be compared like-for-like with shavings
  • Chopped hay and straw is more expensive per cubic foot than pine shavings almost everywhere
  • Hay-based bedding holds moisture differently from shavings and needs watching in a damp coop

Skip it if. Your coop is well away from neighbors and well ventilated. Plain pine shavings do the job for less.

  • 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.

FAQ

Questions people actually ask

What is the best bedding for a chicken coop?

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.
