Exhaust fans, although present in almost every poultry house, are often under-used. One of the most common arguments against using exhaust fans and for using side wall curtains is electricity usage. After all, curtain ventilation is "free" and fan ventilation costs money. Though it is true that producers who curtain ventilate their houses during cool weather will have lower electricity costs, the question is whether they really save a lot of money by doing so?
