Just recently had a similar situation. We adopted this cute sweet lab mix to protect our animals on our mini homestead from coyotes and foxes.
Our dog killed a chicken after being so good with them randomly one morning. We didn’t even think it was her at first, until we saw the second attack.
She attacked another and we tried everything we could to teach her “our birds.” I’ve never had an issue with past rescue dogs and my girl she was A very smart lab mix. Maybe too smart- She broke into the pen finished the one she attacked earlier-except hid it from us until later to bring it out and eat her. She just got better at hiding it
One of our favorite ducks went missing and I knew then , she did it again and We couldn’t break her and our trust in her was gone. She just learned to hide the bodies.
We took her with all her stuff to a local rescue and are donating for her care. Hoping she finds a perfect family without small livestock. But it’s heart breaking. It’s the first time I’ve ever had to return an animal . But I think where she failed as a farm dog she’d be someone’s dream hunting dog or family dog as she is very sweet. Still it was and is very hard. I’m still not over having to do it.
Best of luck with your situation.
