I'm not suggesting you didn't water them. All I'm saying is temps at 97 aren't lethal in my experience unless chickens don't, IN GENERAL (meaning not you personally), have water. It wasn't a personal attack. And, honestly, I wouldn't think two hours at 97, WITHOUT water, would kill them. Something else happened, in my opinion, not having anything to do with heat (or water).
It's why I suggested a spider or snake bite(s). But I don't have any other suggestions. I'm at a loss. And I'm terribly sorry.
