      Delmarva is where the states of Delaware, Maryland and Virginia come together. Each of the two thousand farms there can house an average of seventy-five thousand chickens.Traditionally the farms used windows to provide fresh air in the chicken house. Farmers rarely planted trees or tall crops around the buildings, so there would be no barrier to the airflow. But then farms began to use new ventilation systems. Instead do windows, the new systems used tunnel fans to circulate air.The fans directed airflow from the poultry houses toward the homes of neighbors.

       德尔马瓦是特拉华州、马里兰州和佛吉尼亚州的总称。那里有2000家农场，每家农场平均能够饲养75000只鸡。农场一般都是通过采用窗户作为养鸡房空气流通的设备。养猪场主很少在养殖场周围种植树木或者高大的农作物，这样便不会给那里的空气流通造成障碍。可是后来，这些农场开始使用新的通风系统。这种新的系统取代了窗户，即采用隧道风机使空气循环流通。这些风机将气流从一个养殖场引向了另一个养殖场。
