Well, we had a preadator get ahold of two of our chicks. My dog. This is how it happened. My Girlfriend was over for dinner. She saw my Girls (dogs) sitting at the back door, like they do when they have to go potty. And she let them out forgetting that the chickens were in the back yard. My dogs are not allowed out without supervision because they are dogs and will want to kill the chickens. Well, they were unsupervised because my Hubby and I didnt know she let them out. My husband went out to clean the grill and found the chicks dead. My daughter saw the carnage and well, my dogs absolutely cannot be blamed for what happened. It was an accident. So the lesson learned. Make sure that guests know the chickens are free ranging and not to let your dogs out without supervision. So sad about our baby chicks. So very sad.
