Guidelines for Operating Tunnel-Ventilated Broiler Houses

One of the first questions a grower with a new tunnel-ventilated house will commonly ask is, "How do I operate it?". This question is usually followed by about a dozen more specific questions. For example:

How many exhaust fans do I run and at what age?
When do I use my fogging system?
When do I go to tunnel ventilation? What age? What temperature?
When should I use natural ventilation?
