Bedding and Cleaning: Deep Litter, Shavings, Sand and Composting Chicken Manure

Chickens produce a surprising amount of manure, and in a closed coop it matters what it lands on. Bedding soaks up moisture, insulates the floor, cushions the birds and keeps smells down. A well-managed bedding system keeps the flock healthier and the keeper's work manageable. A poor one produces ammonia, flies, parasites and respiratory trouble.

This guide compares the common choices and explains how to keep a coop clean without spending your life with a shovel. Climate, coop design and flock size change what works best, so treat these as starting points.

What Bedding Has to Do

• Absorb moisture from droppings and spilled water.
• Insulate the floor in winter and stay dry.
• Control odor and ammonia.
• Cushion hens that come down from roosts, which matters for heavy breeds.
• Be safe if pecked or eaten, and free of mold and toxins.
• Be affordable and available.

The Main Choices

• Pine shavings. Widely used, absorbent, easy to clean and generally low in dust when the right grade is chosen. Avoid cedar, which has strong aromatic oils, and avoid fine dusty shavings. Use clean, untreated wood only.
• Straw. Cheap and good for nest boxes and insulation. It absorbs less moisture than shavings, mats down and can grow mold if it stays damp. Chopped straw works better than long straw.
• Sand. Coarse sand stays cleaner and can be sifted like cat litter, and it does not hold moisture the way organic bedding does. It is heavy and cold in winter, and not ideal in damp climates. Use coarse construction-grade sand, not fine play sand, which can be dusty.
• Hemp and other specialty bedding. Highly absorbent and low dust, but more expensive and not available everywhere.
• Leaves and wood chips. Useful in runs. In the coop they can hold moisture and mold, so use clean, dry material.

Whatever you pick, avoid moldy material. Mold spores can cause serious respiratory illness in birds, as the Merck Veterinary Manual poultry section explains for fungal diseases.

The Deep Litter Method

Deep litter is a way of letting bedding build up in layers, adding fresh material on top and turning it occasionally so droppings break down in place. Done well, it produces a dry, crumbly layer, stays relatively odor-free and generates a little warmth. Done badly, it becomes a wet, smelly, ammonia-laden mess.

1. Start with a few inches of dry bedding.
2. Add fresh bedding when the surface looks dirty or damp.
3. Stir or turn the litter regularly to mix droppings in and let air in.
4. Remove wet spots, especially under waterers.
5. Clean out fully once or twice a year, often in spring or fall, depending on your climate.

The method works best in a dry, well-ventilated coop. In wet climates or tight, humid coops, it can fail, so check for odor and dampness. Good airflow is covered in the coop design guide.

Droppings Boards and Pits

Roosting birds drop much of their manure at night. A droppings board, a removable tray or board under the roosts, collects it so you can scrape it daily or weekly. Covering the board with sand, shavings or a layer of sheeting makes cleaning easy. Removing night droppings keeps the main floor drier and reduces ammonia. It also lets you look at droppings for signs of illness, which the parasite guide encourages.

Ammonia and Moisture

If you smell ammonia when you open the coop, it is too strong for the birds. Ammonia irritates eyes and airways and can predispose birds to respiratory disease. The cure is dry bedding, good ventilation and cleaning more often. Common wet sources are leaking waterers, spilled water and condensation. Place waterers on a raised platform or over a mesh, and repair leaks quickly.

Nest Boxes

Use soft, clean material that keeps eggs cushioned and clean. Straw, shavings or nest pads all work. Replace material when it is soiled. Clean nest boxes keep eggs clean, which matters for eggs you sell, as the guide to selling backyard eggs discusses.

Cleaning Routine

• Daily. Remove wet bedding spots and clean droppings boards if you use them.
• Weekly. Stir deep litter, refresh bedding and check waterers and feeders.
• Seasonally. Clean out the coop completely, scrub perches and nest boxes and let it dry in the sun when possible.

When you clean, wear a dust mask and gloves. Dry litter dust can carry germs and irritate lungs.

Composting Chicken Manure

Chicken manure is rich in nitrogen and makes excellent garden fertilizer, but fresh manure is too strong and can burn plants and carry pathogens. Composting breaks it down and reduces risks.

• Mix manure and bedding with carbon-rich materials such as leaves or straw.
• Keep the pile moist like a wrung-out sponge and turn it periodically.
• Let it finish. Many gardeners age it for several months before use.
• Keep it away from water sources and the coop, and cover it to prevent runoff.
• Do not use fresh manure on crops you will eat soon. Food safety guidelines for manure use on edible crops include waiting periods, so check your state's guidance.

ATTRA and extension programs provide composting guidance for small farms. Wash your hands carefully after handling manure, since poultry carry germs like Salmonella, as the CDC backyard poultry guidance explains.

Common Mistakes

• Letting bedding stay wet. It breeds ammonia and mold.
• Using cedar or dusty material. It irritates airways.
• Deep litter in a damp coop. It fails without airflow.
• Using fresh manure on the garden. It burns plants and carries germs.
• Skipping the dust mask. Lung irritation builds.
