Our weather forecast calls for 100 degrees tomorrow and the day after that and the day after that... I've already been putting my flock in a chicken tractor parked in the deepest shade in our yard, plus I wet the grass inside down every hour, plus I put ice in the waterer and give cold treats like watermelon. I'm thinking about adding some kind of portable fan to set up outside the tractor and pointing at one end of it, so the chickens can get out of the breeze if they choose to. I've been browsing at the home improvement stores online, but most of the fans seem to be rated only for indoor use. Does anyone here have a recommendation for a fan that they like?
