I'm letting them choose where they want to ride out the storm. If they want to stay under cover they can. If they want to be outside they can. It is open where their paddock is so I am not worried about falling trees. It will be interesting to see where they choose to be. Most storms they just hang out in the open. The only time they really use the shelter is when the bugs are out since the shelter is dark and the bugs don't tend to go in it.
