The depth of wood shavings inside a poultry house is one of the most important factors affecting litter quality, moisture levels, ammonia buildup, and bird comfort.
Too little bedding increases moisture, while too much increases costs unnecessarily.This guide explains the ideal bedding depth for different seasons, house types, and shavings types.
Why Bedding Depth Matters
Correct bedding depth helps:
Absorb moisture
Reduce ammonia
Improve bird comfort
Prevent footpad dermatitis
Maintain floor temperature
Keep the litter dry longer
Ideal Bedding Depth by Season
1) Summer
Moisture is lower, and temperature is higher.
Ideal depth:
5–7 cm
2) Winter
Moisture increases and birds need more warmth.
Ideal depth:
8–10 cm
Best Depth by House Type
Closed System Houses
Good control of temperature and humidity.
Ideal depth:
5–7 cm year-round
Open Houses
More exposure to weather and humidity.
Ideal depth:
Summer: 6–8 cm
Winter: 9–12 cm
Best Depth by Shavings Type
White Pine Shavings
High absorption → need less depth
Recommended:
5–7 cm
Mixed Wood Shavings
Lower absorption → need more depth
Recommended:
7–9 cm
Compressed Shavings
Expand after fluffing
Recommended:
6–8 cm
Adjusting Depth Based on Stocking Density
Higher bird density increases moisture.
