In the poultry industry, proper ventilation is critical for maintaining optimal air quality, reducing ammonia levels, and preventing heat stress—key factors that directly impact egg production and flock health. This guide explains how natural wind pressure and mechanical ventilation work together in layer chicken housing systems, identifies common issues like airflow dead zones and gas buildup, and offers actionable solutions such as strategic fan placement, cage reconfiguration, and smart monitoring tools. Using real-world examples from farms using Zhengzhou Livvi Mechanical’s H-type multi-tier chicken cages, this article shows how design innovations can significantly boost airflow efficiency—resulting in healthier birds and higher yields. Whether you're managing a small farm or large-scale operation, these practical tips will help you optimize your environment for better outcomes.
