I am so upset. This morningour three barnvelders were great, right before lunch we looked out to find two big dogs had torn into the coop and killed them all! We have tried to be so careful, and the coop is in our fenced back yard! My hubby is beside himself. Not sure what we will do now... But if we get more we will have to rethink our pen since apparently a large dog can rip right into it!
