I have a small pre-fab coop/run, with three young birds. This week, our temps are ranging from highs of 108-101, Sun - Sat. My coop/run is under trees but gets afternoon sun, so I put up a 10X10 Cool-a-roo shade awning Saturday, and I've been experimenting with one of those free-standing misters from Home Depot, on a timer. But, each time it goes off, my three girls HIDE from the water, under the coop! This time I was curious to see if the higher temperatures would temp them to be under the mist at all. Nope! The only thing that appeared to benefit from the moisture was flies, as it turned my nice, dry sand run into fly nirvana. So I removed the misting system. I've got solar powered fans on order, and today at lunch I'll run an extension cord back there for a fan, until those arrive. I'll put a cake pan in the run, full of ice, for dipping feet & beaks, with a couple of frozen water bottles. Anything else anyone can think of, to keep my girls from melting?
