Methods & Assumptions
    Disclaimer: This calculator provides an engineering estimate for planning and comparison. Poultry houses, equipment, birds, weather, and integrator requirements vary. Confirm major ventilation, heating, cooling, and animal welfare decisions with your integrator, poultry technician, extension specialist, equipment manufacturer, or poultry house engineer.

    Litter Drying Dynamics During Preheating

    Ensuring litter is dry and warm before chick placement is vital. Damp litter encourages pathogen growth and ammonia release, which damages the chick's eyes and immune system.

    Drying litter effectively requires more than just heat; it requires air movement (air velocity) over the litter surface and enough minimum ventilation to remove the moisture-laden air. Circulating humid air without exhausting it will saturate the house and halt the drying process.

    Frequently Asked Questions (FAQ)

    What moisture should litter be at chick placement?

    Use your integrator guidance. Many discussions around preheating target dry, friable litter and often mention around 15% to 20% moisture at placement.
