The University of Georgia recently conducted research to study how excess leakage in a small area – like along the end wall fans – can impact litter quality, fuel usage, and ultimately bird welfare.

Drafts are abundant near the fans on the side or end wall. Birds tend to get sick in these areas and litter quality is damper.

This study compared two houses: one equipped with fan caps, the other with fan socks. These covers increase the static pressure in the house and prevent hot air from leaving. You may see them billow out a bit, then deflate when minimum vent fans come on, and that warm air is pulled back into the house.

The covers resulted in warmer houses over all, drier floors, and better bird distribution. To learn more about the mechanics and results of this study, you can watch the video here.
