Well, in our cage, there is an inner coup and an outer coop. The outer coop allows them to run around, etc, and inside the outside coop is an inner coup, which is where they all sleep. The wind here is so bad that some trees (not huge trees) are snapping. They have a heat lamp inside, food, and water. They are all huddled up. So I'm thinking, if the wind makes the outside coop unstable or it blows down - They'd still be inside the inner coop, and the wind wouldn't "take them away".
