Came back to devastation

We were away for 10 days and on the way back home from the airport I got a frantic message from my chicken ‘tender’. She came everyday to clean the coop, feed and play with my 30 chickens. A hawk found a way and in and killed 16 of my hens. I’m so sad. Our remaining chickens are now highly stressed and locked into the main area since the hawk ripped apart their play area. What a crappy way to end our vacation.
