I provide all of mine with ice water fairly regularly, and there's plenty of shade. I let the pigs root around in their mudhole more often than usual to keep the sun off them. I have a water mister for the chickens and quails. I've thought about installing a swamp cooler of sorts in the chicken coop, but I'm afraid that might lead to moisture building up which isn't healthy for them. I have fans running which provides some relief, plus they help keep the flies away too. It really is hot right now!
