Tunnel ventilation

The key to keeping birds cool during the warm summer months is air movement. If enough air is moved over and around a bird the effective air temperature can be reduced by ten degrees or more. This is because as air moves over the bird, heat is removed from the bird's body, making it cooler. So, even though a thermometer in a house may indicate that the air temperature is 85°, with good air movement the birds will eat, gain weight, and perform as if the temperature were 75°.
