Big birds benefit more from tunnel ventilation
US - The most successful big bird operations are using higher wind speeds when using tunnel ventilation to create a "wind chill" to keep birds cool and flocks productive. Keeping birds body temperatures within normal ranges keeps the birds eating and growing and makes a flock more productive.
Tunnel ventilated poultry houses rely on high wind speeds generated by tunnel fans to produce a "wind-chill affect" and make birds more comfortable during hot weather. Moving air removes sensible heat from the birds without any energy expended by the birds themselves. Keeping bird's body temperatures within normal ranges, even during periods of extremely hot weather, keeps the birds eating and growing and makes a flock more productive.
