I've read that they will use a shallow kiddie pool, but have never tried myself. I have soaked hens with bad butt in water and they don't seem to mind that. If you try a kiddy pool, be sure they have easy access in and out and let us know what happens. I don't get overly hot (it's 84 today which is way too hot for me, but I do sympathize with you folks who regularly hit the 90s and triple digits. Personally, I'd move although that is not always an option.
