You don't live too far from me! I'm in Lenore, just above the Clearwater, and I know how bad the wind is. But, none of my trees are stressed from it. I do have a cherry tree in our little orchard, and it's doing fine. I think we've only watered the orchard once or twice this year. The deer are doing major damage to the trees, but they don't seem to be affected by the wind. Our neighbor has several huge cherry trees, and she doesn't water them, and they are thriving. But, she does have some other trees that block some of the wind, so maybe that is why? I'm no expert on trees though, so I don't know how tough cherry trees are. If the tree is the only thing that is providing shade for the chickens, you could always build something for shade, until you get another tree.
