Pine shavings beat sand and hemp for most backyard coops

For a first-time keeper in a temperate US climate, the answer is kiln-dried pine shavings, large flake, ~3-inch depth, refreshed weekly — and it isn't close. Pine is the bedding that goes wrong least often. Sand earns its keep in hot, dry climates where you'll actually scoop daily; hemp is the premium long-life pick once your flock crosses a dozen birds; straw is acceptable only as deep-litter base or in nest boxes. Cedar is toxic to poultry — skip it regardless of how the bag is marketed.

The cedar warning is settled across Cooperative Extension small-flock publications. The pine/sand/hemp/straw rankings below are a synthesis of practitioner consensus and what holds up under the climate and time-budget realities most backyard keepers actually run.

Side-by-side comparison

Pine shavings — the default

Pine shavings work for almost every backyard flock. The reasons are practical, not romantic: feed stores stock them everywhere in 8–10 cu ft compressed bales for $7–10, kiln drying knocks most of the dust out, large-flake size doesn't pack down as fast as fine, and they compost cleanly with the manure.

Specifications:

Type:kiln-dried pine, large flake. Avoid “fine” or “medium” — finer grades create more dust.
Depth: 3–4 inches for routine maintenance, 6+ inches if running deep-litter.
Refresh schedule: top up weekly (small bag each time), full clean-out monthly.
Dust check: if you see a visible cloud when you stir the bedding, the bag is too fine. Switch brands.
Cost: ~$8 per 8 cu ft compressed bale, covers a 4×8 coop for 4–6 weeks.

One opinion the marketing won't share: skip the “fine” and “medium” grades entirely. They're a dust mask waiting to happen — the chickens shake it off, but you'll feel it on your lungs by the third cleanout. If a bag puffs visibly when you tip it into the coop, switch brands; the next bag of large-flake from a different mill usually behaves.

Sand — for hot/dry climates

A 6–8 in layer of coarse construction sand on the coop floor works well in arid climates (Phoenix, Las Vegas, central Texas, southern California inland). The advantages:

Thermal mass. Sand stays cooler than wood shavings in summer heat — the floor stays 5–10°F below shavings-bedded floors during peak afternoon temperatures.
No decomposition.Sand doesn't mold, doesn't compost, doesn't need replacement. You scoop out droppings daily with a kitty-litter scoop or a small rake; the sand itself lasts 1–2 years before needing full replacement.
Drainage. Spilled water drains away instead of soaking into bedding.
Hen comfort. Hens love dust-bathing in sand — saves you from building a separate dust-bath area.

Sand only earns its keep if you actually scoop daily. Skip three days in July and you'll wish you'd bought pine — droppings accumulate, ammonia rises, and the easier-than-pine claim falls apart fast. Sand is also heavy: 6 inches in a 4×8 coop is roughly 1,500 lb, which the floor framing must support before you start dumping bags.

Use coarse construction sand (also called concrete sand or all-purpose sand). Not play sand — too fine, dusty, and creates respiratory problems with sustained exposure. Bag-grade construction sand from a hardware store (~$5/50 lb bag) or bulk-delivered from a landscape supplier (~$30/cubic yard) works.

Hemp bedding — premium long-life

Hemp hurd (the inner core of the hemp stalk, processed into short fibers) outperforms pine on absorbency by roughly 2–3× and decomposes more slowly, giving you a 2–3-week refresh schedule instead of weekly. Lower dust than pine, cleaner composting profile, marginally better odor control.

The tradeoff is cost. Hemp runs $25–40 per 25–30 lb bag versus $8 for an equivalent volume of pine. Per-week cost works out to about 1.3× pine — modest if you value the time savings, significant if you have a 12+ bird flock and budget pressure.

Availability is the other limiter. Most farm stores don't stock hemp; you'll order online (Aubiose, Old Dominion Hemp, etc.). Plan ahead and order monthly.

My read: hemp earns its price tag once your flock crosses about a dozen birds, or any time the binding constraint is your weekend rather than your wallet. Below 6 birds, I'd stay on pine and spend the difference on better fencing.

Straw — acceptable, not great

Straw (wheat, barley, oat — not hay, which is too high in moisture and seeds) is the historical bedding from before shavings were widely available. It still works, but pine beats it for most backyard scenarios:

Mats faster. The hollow stalks compress into a wet pad within days under chicken traffic.
Holds moisture. Less absorbent per volume than pine.
Harder to compost. The high-carbon stalks take 6+ months to break down vs 2–3 months for pine.
Mites can hide in it. The hollow stalks are excellent red-mite habitat in warm humid climates.

Straw is fine. It's not great. Use it as the base layer of a deep-litter system or for nest boxes — where it's cleaner and changed weekly — and don't run it as primary floor bedding. The historical romance is real; the practical case for it as the main coop floor in 2026 isn't.

Cedar — never use

Cedar shavings are sold widely as small-pet bedding. The aromatic oils that smell pleasant to humans (and deter moths and some insects) are respiratory toxins for poultry. Plicatic acid and the terpene fraction damage avian airway tissue at chronic-exposure levels. Reported effects include chronic respiratory disease, suppressed laying, and increased susceptibility to other infections.

Avoid cedar. Just don't. No cedar shavings, no cedar dust, no cedar-pine blends, no cedar block tucked behind the nest boxes as a “natural moth deterrent.” The aromatic-cedar marketing isn't worth a chronic respiratory issue you'll spend the next two years trying to diagnose. Published Cooperative Extension guidance is consistent on this — cedar is not a poultry bedding.

Frequently asked

What is the best bedding for a chicken coop?

Kiln-dried pine shavings (large flake) are the default for the majority of backyard flocks — cheap, absorbent, low-dust, easy to refresh. Sand works better in hot/dry climates because it doesn't decompose. Hemp bedding is the premium choice (lasts 2–3× longer than pine) when budget allows. Straw is acceptable as deep-litter under pine but mats fast and holds moisture. Avoid cedar shavings entirely — the aromatic oils are respiratory toxins for poultry.

Can I use cedar shavings in a chicken coop?

No. Cedar shavings release plicatic acid and aromatic terpene oils that damage avian respiratory tissue — chickens have substantially more sensitive airways than mammals. Long-term exposure causes chronic respiratory issues, reduced egg production, and increased disease susceptibility. The aromatic-cedar marketing as 'natural pest deterrent' is true for moths but the cost to bird health is too high. Pine, sand, hemp, or straw are all safer.

How deep should bedding be in a chicken coop?

3–4 inches for routine bedding; 6–12+ inches if you're running deep-litter (a managed compost-in-place system that builds beneficial microbes over the season). Less than 2 inches and droppings reach the floor too fast, accelerating ammonia buildup and rotting the floor. More than 4 inches without active management compacts and goes anaerobic. The deep-litter method works only if you actively turn and add to the bed every 1–2 weeks.

Is sand good bedding for chicken coops?

In hot, dry climates yes — sand drains well, dries quickly, and you sift droppings out daily with a kitty-litter scoop. Coop stays cooler than wood-shavings coops because sand has higher thermal mass. In cold or humid climates sand is the wrong choice — it stays cold, can hold ammonia under crusts, and freezes solid in winter. Use coarse construction sand (concrete sand), not play sand (too fine, dusty, can cause respiratory issues from prolonged exposure).

How often should you change chicken coop bedding?

Frequency depends on the system. Routine pine-shavings setup: refresh weekly (top up where it's wet), full clean-out monthly. Sand: scoop droppings daily, full sift weekly, deep clean-out 1–2× per year. Deep litter: top up biweekly with fresh material, never full clean-out until spring (or fall, depending on climate). The signs you've waited too long: ammonia smell when you enter the coop, visible damp patches, mold spots, hens reluctant to enter.

Should bedding be different in nest boxes vs the coop floor?

Yes, slightly. Nest boxes need clean, soft, dry material because eggs sit in it directly — pine shavings (the same kind as floor), straw, or hemp work. Aspen shavings are also good for nest boxes (more expensive but very soft). Sand is wrong for nest boxes — abrasive on egg shells, cold against the brooding hen. Refresh nest box bedding weekly regardless of floor schedule. A 1–2 in layer is enough; deeper just gets kicked out.
