Sadly, we lost our beloved one-year-old chicken Peach to our own pet dog on Monday and I'm sick about it because essentially it was my fault. We just moved and didn't realize we had a hole in the side of our run when we set it back up, and our 9-month old German shepherd got her. So, we redid the run with extra thick wire stapled to the frame. An hour ago, my husband looked out and there were the remaining 3 hens, who had been locked in, huddling by our back door. The dog had ripped the side off the new run with her teeth. Two questions: one, has anyone ever heard of a dog being able to be trained to protect, not play with or kill, chickens? We are about to start a 6-week training program but have been told by that training facility that dogs will always chase and kill chickens. Second: anyone have suggestions for building a run that the dog can't rip off? Thanks for your help.
