Sounds like here on the Maryland coast. Temps in the 90's ... heat index near 110 ... and the County Fair starts Friday. My poor biddies will be traveling and strutting their stuff for the judges this weekend, boor babies. No extra fans are allowed, so we have one cooler full of frozen water bottles and another full of zip-lock bags full of ice cubes. They'll be rotated through our cages all day long. I'll try to get a picture of the ice loungers; my boys know how to "chill!"
A word to the wise for anyone who wants to try this trick: Don't put refrozen water bottles in with your family's food. If you don't have a livestock-dedicated freezer, keep the bottles in a lidded bin, so you don't cross-contaminate your dinner. We actually use empty bottles out of our recycle stock. We fill them with weakly-colored water before super-gluing the lids back on. That way, no one is tempted to drink them and if they spill, the color reminds you to be careful with cleanup. A totally welcome side benefit is that DD does't want the colored water to stain her birds' feathers ... so she cleans it up quicker!
