I am disgusted and confused right now. I have had darla for about 3 years now. I have always been proud of what a great guard dog she is. She has been around newborn kittens, rabbits and chicks without incident. I let my hens hatch and raise their chicks on their own since darla had always kept them safe. Today I heard a commotion. Darla had ran up and grabbed a chick. I was yelling at her to drop it and she just looked at me and ate it. I felt like killing her. I don't know what to do now. I know she obviously can't be trusted around chicks, but what about the adults? Should I assume she is going to decide they are lunch too?
