The best bedding for ducks is one that absorbs moisture quickly, stays dry on the surface, and doesn’t create dust or mold problems. Pine shavings, hemp, straw, and rice husks are the most popular options, but each has trade-offs depending on your setup, your climate, and whether you’re bedding a coop, a brooder, or an outdoor run. Ducks produce far more moisture than chickens, both from droppings and from splashing water everywhere, so absorbency matters more than almost anything else.
Why Bedding Choice Matters for Ducks
Bedding does four jobs: it cushions your ducks from hard flooring, absorbs moisture from droppings and spilled water, dilutes waste so the top layer stays relatively dry, and insulates against cold floors. When bedding fails at any of these, problems stack up fast. Wet, compacted litter drives ammonia levels higher (the U.S. threshold for safe ammonia in poultry housing is 25 parts per million), encourages the growth of harmful fungi and bacteria, and softens the skin on your ducks’ feet.
That soft, damaged skin is how bumblefoot starts. Damp or unsanitary bedding, combined with rough or uneven surfaces, creates the perfect conditions for bacterial infections on the foot pad. Keeping bedding dry and providing a soft, even surface to walk on is one of the simplest ways to prevent it.
Pine Shavings
Pine shavings are the most widely available and commonly recommended bedding for backyard ducks. They’re affordable, easy to find at farm supply stores, and simple to spot-clean. Pine sawdust absorbs about 2.5 pounds of water per pound of bedding, while larger pine shavings absorb closer to 1.5 to 2 pounds per pound, so finer cuts hold more moisture but also produce more dust.
Dust is the main downside. Wood shavings can cause respiratory irritation in ducks, particularly the finer sawdust grades. Using kiln-dried, large-flake pine shavings reduces this risk. Avoid cedar shavings entirely. Cedar contains aromatic oils that are toxic to birds and can damage their sensitive respiratory systems. This applies to all poultry, not just ducks.
Hemp Bedding
Hemp bedding has become increasingly popular for duck keepers, and for good reason. It outperforms pine shavings in moisture absorption, keeping the surface of the coop drier even with ducks’ heavy water use. It’s a lightweight, porous material that clumps around wet spots, which means you can scoop out only the soiled areas and leave the rest. This extends the time between full bedding changes and reduces overall cost despite a higher upfront price per bag.
Hemp also does a noticeably better job controlling ammonia. Duck owners frequently report a significant reduction in ammonia smell after switching from wood products. On the back end, hemp breaks down quickly in a compost pile and incorporates duck waste into nutrient-rich compost, while wood shavings can take much longer to decompose. A single compressed bag of hemp bedding typically expands to cover far more floor space than the equivalent weight of pine, so the cost difference narrows when you factor in coverage and how long each change lasts.
Straw
Straw is cheap, widely available, and provides excellent insulation in cold weather, which makes it a popular winter bedding. Chopped oat straw absorbs about 2.4 pounds of water per pound of material, roughly comparable to pine sawdust. Ducks also seem to enjoy nesting in it.
The serious risk with straw is mold. The fungus that causes aspergillosis, a potentially fatal respiratory infection, thrives in warm, moist, decomposing organic matter like straw and grain. Captive birds become infected by inhaling fungal spores from moldy bedding. Young ducklings are especially vulnerable. If you use straw, inspect it carefully before putting it in the coop. It should smell clean and dry, never musty. Replace it frequently, because straw mats down and traps moisture underneath faster than shavings or hemp, creating exactly the warm, damp conditions where mold flourishes.
Rice Husks
Rice husks are the dominant poultry bedding material in parts of Asia, used in roughly 85% of duck and broiler operations. Research from a 42-day trial with Pekin ducks found that rice husk bedding produced higher daily weight gain and elevated body weight compared to other materials tested. They’re lightweight, resist compaction, and don’t break down as quickly as straw.
Availability is the limiting factor. If you’re in a rice-growing region, husks can be inexpensive or even free. Elsewhere, they may be hard to source. They’re a strong option if you can find them locally.
Coco Peat
Coco peat (also called coir) is made from coconut husk fiber. It readily absorbs water and dust, is lightweight and easy to handle, and has a naturally slightly acidic pH of around 5.5 to 6.5. That acidity helps slow the growth of bacteria and other pathogens. It’s also essentially pathogen-free when purchased, highly renewable, and breaks down slowly, meaning it lasts a while before needing replacement.
The downsides are cost and availability. Coco peat is more expensive than straw or pine shavings in most markets, and it’s not stocked at every farm supply store. Some duck keepers use it as a supplement, mixing it with shavings or hemp rather than using it as the sole bedding material.
Sand
Sand works well in some situations but poorly in others. In a covered run with good drainage, coarse construction sand lets water pass through quickly and makes scooping solid waste easy, similar to a cat litter box. It doesn’t harbor mold, doesn’t break down, and doesn’t need regular replacement.
For duck housing specifically, sand has real limitations. It holds moisture in wet climates and can start to smell. It provides no insulation in cold weather, and it’s heavy, making full cleanouts a chore. Sand also does nothing to absorb the ammonia from duck droppings the way organic bedding materials do. It’s best suited for outdoor areas with overhead cover and good ground drainage, not for enclosed coops where ducks sleep overnight.
What to Use for Ducklings
Ducklings in a brooder need bedding that won’t cause two specific problems: slipping and impaction. Smooth surfaces like newspaper or bare plastic cause ducklings’ legs to splay outward, a condition called spraddle leg that can become permanent if not corrected quickly. At the same time, very young ducklings peck at and eat everything, so fine materials like sawdust or sand can cause digestive blockages.
For the first week or two, the safest option is non-slip rubber shelf liner, the textured kind sold for kitchen drawers. It gives ducklings solid footing, is easy to rinse clean, and eliminates the risk of ingestion. Once ducklings are a bit older and less inclined to eat their bedding, you can transition to large-flake pine shavings or hemp. Avoid straw for very young ducklings because of the heightened aspergillosis risk in brooder-age birds, a condition historically known as “brooder pneumonia” in hatchery settings.
Keeping Ammonia Under Control
Ducks produce wetter droppings than chickens, which means ammonia builds up faster. At concentrations above 25 ppm, ammonia damages the respiratory tract and reduces egg production. Research on Muscovy ducks found that ammonia exposure at 75 ppm significantly decreased egg laying, and the safe threshold for duck houses likely falls somewhere between the U.S. standard of 25 ppm and much higher levels where obvious harm begins.
The simplest test: if you can smell ammonia when you walk into the coop, levels are already too high. Choosing a highly absorbent bedding like hemp or pine shavings helps, but no bedding eliminates ammonia on its own. Ventilation is equally important. Your coop needs airflow above the ducks’ heads, even in winter, to carry ammonia and moisture out. Spot-cleaning wet patches daily and doing full bedding changes on a regular schedule, weekly in most setups, keeps ammonia manageable.
Some keepers use the deep litter method, layering fresh bedding on top of old material and allowing beneficial microbes to break down waste over time. This can work with ducks, but it requires careful management because of how much moisture ducks add. If the deep litter stays too wet, it becomes exactly the kind of compacted, anaerobic environment that produces the most ammonia and mold. Stirring the litter regularly and adding generous amounts of fresh material on top are essential if you go this route.
