Hot and humid is the worst! Mist might help, but maybe not. Ice in the waterers and cooler ground for dust bathing helps. Cooling off the roof with the hose definitely helps, and fans to move the air better. Mary
x2! They need to be in the shade! Mist/ wet down the coop roof, at least in the afternoon. Add a fan in the coop to provide good air flow. Select breeds that handle heat better too; not the cold weather types that work so well further north. Mary
