Your Nose Knows Before You Do
Walk into any chicken coop and your nose tells you immediately whether the bedding is working: ammonia stings your eyes and moisture mats the floor — or everything smells earthy, hens scratch contentedly and eggs come out clean. The difference almost always comes down to the material beneath their feet.
Bedding (also called litter) affects respiratory health, foot integrity, egg cleanliness, parasite pressure, winter warmth, labor hours and annual costs. It's one of the most consequential decisions a poultry keeper makes.
Why Bedding Is About More Than Comfort
- Ammonia control: fecal decomposition releases ammonia; above ~25 ppm, chickens suffer corneal damage and chronic respiratory inflammation. Adequate depth and absorbency keep it safe between cleanouts.
- Moisture management: wet litter drives bumblefoot, coccidiosis and respiratory illness; litter moisture above 35% dramatically increases pathogen load on the coop floor.
- Thermal insulation: a deep, dry litter layer — especially with the deep litter method — generates microbial heat that can raise floor temperature 8–12°F (4–7°C) in winter.
- Behavioral enrichment: loose, scratchable bedding enables dust-bathing, essential for feather maintenance and ectoparasite control.
- Egg cleanliness: clean, dry nesting material means cleaner eggs with less washing (which strips the protective bloom).
The 6 Best Bedding Materials
1. Pine shavings — the gold standard
Medium pine shavings absorb moisture well, smell pleasant, are affordable in bulk and compostable. Depth 4–6 in, refresh every 2–4 weeks. Pros: high absorbency, good odor control, low cost, easy to find. Cons: medium dust, clumps when wet.
2. Straw — winter insulation, weak on moisture
Wheat or oat straw is cheap and abundant; hollow stalks insulate well, making it excellent for winter. But absorbency is below average and it molds fast when wet. Depth 4–8 in, refresh every 1–2 weeks in wet weather. Cons: harbors mites, poor odor control.
3. Coarse sand — litter-box style
Construction-grade coarse sand dries droppings quickly for daily scooping, with very little odor and near-zero mite risk — ideal for hot, humid climates. But it offers no winter insulation and needs daily surface cleaning. Depth 3–4 in, replace annually.
4. Hemp bedding — premium performance
Hemp hurd absorbs up to 4× its weight in water, controls ammonia far better than shavings, and is nearly dust-free — the pick for birds with respiratory sensitivities. Depth 3–5 in, refresh every 4–6 weeks. Cons: higher upfront cost, less available.
5. Shredded paper — free but short-lived
Shredded paper and cardboard are near-zero-cost and compostable, but compact quickly, get slippery when wet and mold fast. Best used in nesting boxes rather than full-coop bedding. Replace every 1–2 weeks.
6. Rice hulls — sustainable regional option
A rice-milling byproduct with reasonable absorbency, very low dust and silica content that naturally deters some parasites. Depth 4–5 in, refresh every 2–3 weeks. Worth sourcing where available.
Head-to-Head at a Glance
| Material | Absorbency | Odor control | Dust | Cost | Best for |
|---|---|---|---|---|---|
| Pine shavings | High | Good | Medium | Low | Everyday backyard flocks |
| Straw | Below average | Poor | Low | Very low | Winter insulation |
| Coarse sand | Dries, doesn't absorb | Excellent when scooped | Low | One-time | Hot, humid climates |
| Hemp | Highest (4× weight) | Excellent | Nearly none | Higher | Respiratory-sensitive birds |
| Shredded paper | Good (compacts) | Fair | Low | Free | Nesting boxes |
| Rice hulls | Reasonable | Good | Very low | Low | Regions where available |
Seasonal Strategy
- Winter: go deep (4–6 in+) and use the deep litter method — straw on top of shavings is a classic cold-climate combo that adds insulation and microbial warmth.
- Summer: switch to sand or lighter shavings, scoop more often, and keep moisture out — heat plus wet litter is the fastest route to ammonia and flies.
- Transition seasons: replace the full bedding at least twice a year (spring and autumn) and always after a wet spell.
Quick Rules
- Never use cedar — its oils are toxic to chickens.
- Keep nesting boxes lined with clean, dry shavings or paper; change whenever soiled.
- If ammonia stings your eyes when you open the door, add depth or switch materials — ventilation helps, but bedding is the first line of defense.
- Pair good bedding with good air flow — see our coop ventilation guide — and keep the flock safe outside the coop with electric poultry fencing.
