What Is Wood Ash?

Wood ash is the fine, powdery residue left over after burning untreated hardwood — think logs from your wood stove, fireplace, or outdoor fire pit. It’s loaded with minerals like potassium, calcium, magnesium, and trace amounts of phosphorus, making it an alkaline, nutrient-rich powder with surprising versatility.

Only use ash from natural, untreated, unpainted wood. Avoid ash from charcoal briquettes, glossy paper, or pressure-treated lumber, as they can contain harmful chemicals.

Why Use Wood Ash in the Chicken Coop?

Let’s break down why wood ash is a hidden gem in your chicken-keeping routine:

1. Natural Mite and Lice Control

One of the most common struggles for chicken owners is battling external parasites like mites and lice. Wood ash is a natural desiccant—it dries out the exoskeletons of these pests, killing them effectively without synthetic chemicals.

2. Perfect for Dust Baths

Chickens love dust baths—it’s their way of keeping clean and free of parasites. Mixing wood ash into their dust bathing area helps:

• Smother mites, lice, and fleas
• Absorb moisture and oil from feathers
• Keep their skin healthy

3. Odor Control in the Coop

Wood ash is alkaline and works like baking soda to neutralize odors. Sprinkling a bit in your coop bedding helps keep the smell down, especially in winter when ventilation may be more limited.

4. Mineral Boost for Chickens

Wood ash contains trace minerals like calcium and potassium, which can benefit your flock’s health when ingested in small, natural amounts via their environment or grit.

5. Reduces Coop Moisture

Moisture is the enemy of a healthy chicken coop. Damp conditions breed bacteria, mold, and respiratory issues. Ash absorbs moisture and helps keep bedding dry.

How to Use Wood Ash in the Chicken Coop

Here are the best and safest ways to use wood ash in and around your coop:

1. Mix It into the Dust Bath

Create a dust bathing area with:

• 1 part wood ash
• 1 part sand or dry dirt
• 1 part diatomaceous earth (optional)

Place it in a large shallow bin, kiddie pool, or sheltered ground space, and let the chickens take care of the rest. They’ll instinctively roll and fluff in it.

2. Sprinkle in Coop Bedding

Add a light layer of ash to the bedding during your regular clean-outs. It helps control moisture and neutralize ammonia odors from droppings.

Tip: Use gloves and wear a mask when spreading dry ash, especially indoors.

3. Use Around the Coop Perimeter

Sprinkling ash around the outside of the coop helps deter pests like ants and soft-bodied insects, as they don’t like the texture and drying effect of ash.

4. Compost It (Then Use That Compost in the Chicken Run!)

Wood ash adds alkaline minerals to your compost pile. Compost it with chicken manure, straw, and kitchen scraps—then use the finished compost to enrich your garden or chicken run.

Bonus: Other Homestead Uses for Wood Ash

Once you’ve stocked your chicken coop, don’t throw out the rest! Wood ash can also be used to:

• Enrich your garden soil (especially in acidic beds)
• Repel slugs and snails
• De-ice pathways in winter
• Clean glass (makes an effective paste!)

If you’re heating with wood, you already have this free resource on hand—so why not put it to work? With wood ash in your chicken coop, you can naturally:

• Boost hygiene
• Control parasites
• Reduce odor
• Keep bedding dry
• Add trace minerals

It’s a zero-waste win for any backyard homestead.
