So very sad.
We don't have much trouble with coyotes, but we have hawks. I never let mine out in the back yard without following every step they take. They stay pretty close together. If I yell Hawk, they all run for the back door. We were out one day and a hawk swooped down just above my head. Scared the life out of me. :/
Kay, xxxxx. I'm so very sorry. I remember that from some time ago. Just breaks my heart.
