chicken coops. I use one so I don't have to run power out there in order to cool the chickens.

They sell solar attic fans you can use relatively easily. If the solar isnt the selling point, just a standard attic fan.

Gotta love the one 1* review complaining they don't work at night.
Probably OK for venting small attics / spaces

The listing specifically notes it's to vent "chicken coops, sheds, and greenhouses". I don't know about you, but all of my chicken coops, sheds, and greenhouses are outside, so waterproofing seems pretty useful.

It's just one direction, right? You can't have one side blowing in and one out?

Since it's probably just a 12V setup, depending on your know-how, you can cut/remove the wiring to one of the fans and reverse the polarity. That would make one fan a pusher and one fan a puller.

Or just remove the 4 screws holding the fan in and flip it over.

300–350 CFM is tiny but sufficient perhaps for a doghouse or chicken coop

33YR4GPK still seems to work. Sometimes it can take a couple of tries for Amazon to accept codes.

Update: expired now

Also didn't work for me. First try it said expired. I tried again after seeing that it sometimes takes a couple of tries. Sometimes said invalid, sometimes expired. After 10+ tries (I think), it says "You have exceeded the maximum attempts allowed, please retry after 2 hours." Most of the tries it said invalid, but a few it said expired. Maybe I'll try again later.

If cooling is the goal, and this is something you are installing permanently (greenhouse, dog house, chicken coop, etc.), wouldn't a temperature sensor be important so you aren't blowing out the warmer air when it is cold out? Do you cover this up in winter?
