Bird Migration in Naturally-Ventilated Broiler Houses

There may be an easy and inexpensive way for growers with naturally-ventilated houses to reduce heat stress related mortality as well as increase bird performance during the summertime. It doesn't involve buying more fans, changing fogging systems, or using more electricity. The only thing the grower has to do is install three or four short migration fences, like those placed in tunnel-ventilated houses.
