red fox trying to eat chickens but german shepherds save the day HD

A Red Fox is trying to get to the chickens in the coop run. The run door must not have been secured properly, and it flew open during the panic. The fox then had free access to the hens. While the fox was planning its attack, one of my German shepherds inside noticed something was wrong. I let them out and they chased down the fox and saved the hens!
