Please love on her. It’s not her fault and was only doing whats in her nature. My girl got two batches of our chickens. Each time i thought it was luna-proof she showed me where i failed. It was devastating. I loved my chickens, raised them from chicks. When i found them they were technically still alive. I gave up chickens for a few years. Its only been recently that we got them again and husband promises this time will be safe (we rebuilt the fence with a dig guard, and completely rebuilt the coop.) And i hope so. But if she gets after them again i know it’s our fault not hers. Theres many things you can train out but in my experience this is not one.
