Understanding Why Proper Ventilation Is Crucial for Chicken Houses

Proper ventilation in chicken houses isn’t just a comfort issue—it’s a critical component of poultry health and productivity. When chickens can’t escape excessive heat, their bodies redirect energy from egg production to cooling down, causing productivity drops of up to 25%. A well-ventilated chicken house helps maintain optimal temperature ranges (65-75°F for most breeds) while removing harmful ammonia fumes that can cause respiratory issues.

Inadequate airflow creates dangerous conditions through:

• Moisture buildup that promotes bacteria and fungal growth, particularly deadly aspergillosis
• Ammonia concentration from droppings that can damage chickens’ respiratory systems at levels above 25ppm
• Heat stress that increases mortality rates by 4-8% during summer months
• Carbon dioxide accumulation that reduces oxygen availability, affecting growth rates

Efficient ventilation systems provide multiple benefits including disease prevention, reduced heat stress, and improved air quality. For every 100 birds, you’ll need approximately 500 cubic feet per minute (CFM) of air exchange to maintain healthy conditions. Your ventilation strategy should adapt to seasonal changes—more airflow during summer months and controlled ventilation during winter to prevent drafts while still removing moisture.
