Thursday night/friday morning we lost 10 of our 15 birds. I closed the run door and forgot to close the pop door on the coop. Something got in and killed 9 of my 10 light brahmas that were 9 weeks old and one of my broody prone sexlinks. It ate the heads off of 4 and just bit the jugulars and left the other ones for dead. I feel so guilty and I am just devastated. What could have done this? We have caught raccoons before but what would just eat the head and leave the rest and then go on a killing spree?
