We have a border collie mix and my dog is half Australian shepherd, half American Eskimo- they did not grow up around chickens, but they got used to them and have never killed one. If your dog listens to you and you can monitor it out with the chickens until it understands they're off limits, I think it should be fine. Can't seem to break the collie of running the calves, though. It's actually annoying my bouncy little shepherd won't help me drive them into their coop at night. I always ask her what is the point of being a herder that won't herd, but she just wags her tail like she has no idea what I'm saying....
