Eep! I'm (and the ducks!) glad it doesn't get crazy hot like that too often here! If we have another super hot summer like a few years ago I may invest in a mister, but with the pond they can keep cool. I'll keep in mind next time we have lettuce to chop it finely! Since we have gigantic gardens I like to give them whatever's in season for treats rather than peas all the time since we tend to have major surplus everything when it's in season! We don't grow peas though. Right now we have quite a bit of lettuce so I'll chop some up for them later! They do like the slugs we find on the lettuce!
