Overview

Proper ventilation, lighting, and climate control are critical for maintaining hen health, supporting natural behaviors, reducing disease risks, and achieving stable egg production throughout the year. These factors become especially important during extreme heat, humidity, or seasonal temperature fluctuations common in Vietnam. This guide provides farmers with practical, step-by-step recommendations on how to improve air quality, manage light intensity, and regulate temperature inside poultry houses—using methods that are effective, affordable, and adaptable to different farm sizes.

The recommendations draw from two recognized high-welfare standards:
-FARMS Initiative Responsible Minimum Standards, offering flexible, principle-based guidance ideal for farms beginning their welfare improvements, and
-Certified Humane, a globally recognized, science-based standard that provides detailed requirements for high-welfare poultry production.

Together, these frameworks help farmers create a safer, more comfortable, and more productive environment for their hens while moving toward internationally aligned welfare practices.

Good lighting, ventilation, and climate control are essential for healthy hens and reliable egg production. This guide shows how even simple changes can significantly improve flock welfare and farm performance.

After reading, you will understand:

‍
• How to manage air quality, temperature, and humidity to reduce stress, prevent disease, and protect hens during extreme weather.
• Best practices for lighting, including intensity, duration, and natural-light support to encourage natural behaviors and consistent laying.
• Ventilation methods that work for different farm types, from basic natural airflow systems to more advanced mechanical options.
• Key welfare guidelines from Certified Humane and FARMS Initiative, and how they apply to Vietnamese farm conditions.
-Practical monitoring tips and low-cost adjustments that can make poultry houses safer, cleaner, and more efficient.

This guide helps you create a healthier environment that protects your hens, stabilizes production, and strengthens your transition toward humane and sustainable egg farming.
