I bought this today to install in my new coop. I have been monitoring the temperature inside the coop to see if I need to add more vents. The temp doesn't get much more than 5 above the outside temp but there just wasn't much air moving. I thought about installing a ceiling fan but I didn't like idea. So today I did some research and found this fan, it is made for moving a lot of air. It just plugs in to the outlet and has 3 different speeds. I am probably going to install a temperature switch to turn it on at a desired temp.
