Oh yes, several times. (I work from home so I can keep an eye on them while I'm working.) I change their water because it's so darned hot. And I have big bags of crushed ice in the freezer, so I put ice in their waterers, too and toss some on the ground. And my Sultans like a dish of water in their elevated coop because they spend more time inside. And yes, then later there's treats, and some frozen water bottles to keep them cool and some mist from the garden hose and make sure everybody is still in the shade, pick up eggs - not many of those right now! Find out who wants a hug. Later let them out to play in the yard for awhile before bed if we can, and they will be expecting (demanding) mealworms. And we sit outside and watch ours, too (when it's not too hot to breathe). We call it "watching chicken TV".
