We have a jack-rat and a rottweiller. The rat could care less about the chickens, but the rott loves them. Where the chickens are she is. She will lay outside the coop and watch them. I believe she thinks it is her job. We have 6 laying hens and we HAD 34 meat birds. Currently she is in mourning. really. Her name is Hooch, she is a rescue dog. Best dog I have ever had. Good luck on your search.
