Thank you for the advice! We do have the remaining hen inside, she is doing ok but we are not sure if she will recover. She is eating an drinking, an she is "talking" to us like normal, but she is not standing. She is missing many feathers, broken beak, an has 2 black eyes! We did contact the sheriffs office made a report an are waiting on animal control to contact us, the neighbors response to the ordeal was "sorry that happened, you can shoot my dog, but I dont have time to deal with this I have somewhere to go" an left before the sheriff showed up.... I'm completely heartbroken, the dog completely destroyed the coop, an broke the run an dug under our fence!
