I agree with that. By the time my lab was 6 months, she still went after chickens, her predictor instinct is overly strong. I have worked with her for almost 3 years, and she still salivates when around the chickens, so I make sure she is not left alone. I know, it is a bit of work, but I cannot get rid of her or the chickens, so I am stuck. I am still working on it, but never leave her alone with them. When they are in the orchard, she is in her kennel. Inconvenient at times, but I love her, she is a great dog in all other ways, I still take her out to the coop when I am taking care of the chickens, and make her wait at the door. Hope this will eventually train her to leave them alone, but would not bet any money if one of them went running across the yard. Good luck with your problem, you are responsible for every animal you bring into your home.None of my dogs have unsupervised time with my chickens, keep your dog on a leash and under your control. I wouldn't get rid of the dog.
