This is the best $100 I ever spent. http://www.canadiantire.ca/browse/p...4443271826&assortment=primary&fromSearch=true It's a fan that can go outdoors & hook to a hose to create a fine COOLING mist that effectively can lower the outdoor temp by up to 50 degrees. Will cover 950 square feet since it oscillates. My chickens prefer to stay indoors with the air conditioning in this heat wave, but at least I know when they are outdoors, they are not uncomfortable or risking HEATSTROKE. I can't say enough about how effective this product is.
