How to Use Diatomaceous Earth in Chicken Coops

Diatomaceous Earth (DE) is a naturally occurring mineral powder made from fossilized freshwater diatoms. When using DE around poultry, it is important to choose food-grade Diatomaceous Earth only. Many chicken keepers incorporate it into coop maintenance routines to help maintain a clean, dry environment.

Benefits in the Coop Environment

When used properly, Diatomaceous Earth may help:

  • Maintain dry bedding areas

  • Support overall coop hygiene

  • Reduce moisture buildup

  • Freshen nesting boxes

  • Contribute to a cleaner dust bath area

A dry coop is essential for flock health, and DE is often used as part of a broader sanitation and maintenance plan.

How to Apply in the Coop

🐔 Bedding & Floor Areas

  • Remove old bedding and clean the coop thoroughly.

  • Lightly dust a thin layer of food-grade DE on the coop floor.

  • Add fresh bedding (pine shavings, straw, etc.).

  • For ongoing maintenance, lightly sprinkle and mix into bedding as needed.

Use a thin layer — more is not better. Excess dust can become airborne.

🥚 Nesting Boxes

  • Sprinkle a small amount beneath nesting material.

  • Replace nesting material regularly to maintain cleanliness.

🐓 Dust Bath Areas

Chickens naturally dust bathe to maintain feather condition.

  • Mix food-grade DE into dry soil or sand in the dust bath area.

  • Ensure the area remains dry and well-ventilated.

🐥 Adding to Feed (Optional Use)

Some poultry owners mix food-grade DE into feed.

  • Typical ratio: up to 2% of total feed weight

  • Mix thoroughly to prevent clumping

  • Provide continuous access to fresh water

Always introduce gradually and consult a poultry health professional if unsure.

Important Safety Guidelines

  • Use food-grade DE only (never pool-grade)

  • Apply when birds are not confined in tight, enclosed spaces

  • Avoid creating heavy airborne dust

  • Wear a mask during application

  • Store in a dry location

While Diatomaceous Earth is widely used in backyard flocks, it should be part of a complete coop management plan that includes regular cleaning, proper ventilation, predator protection, and routine flock health monitoring.
