Fans inside the coop?

[RRM]

I use a box fan in an east window to blow cooler air into the coop late in day.
Never leave it running overnight, I turn it off when I lock up after dark.
It does help.

This is a very good idea if your coop is hot!
Our walk-in door is on the east side of the coop, so we sometimes leave it open before the chickens come back from free ranging if it is super hot. Our coop is in the shade from daylight to dark so most times it’s fine inside due to the large vent openings on all four sides.
