We have 2 shep mix and 1 pure golden ret dogs. The mixed breed dogs were the worst about killing, baby wild turkeys, rabbits, chipmunks..to many to list. I said I would never let the chickens free range when the dogs were loose on the property. Boy was I wrong. The dogs LOVE the chickens! The chickens lived in the run for about 2 months where the dogs could see, smell, but not touch them. Once we decided to try and let them out together I took each dog one by one and made them lay on their backs, then I held chicken over them and poked them with my finger. The dogs have never looked like they would like to hurt the chickens, even when the chickens run right by them with their wings flapping. The dogs take turns watching them and they never leave the chickens unattended.
