We live in the country and our chickens free ranged, one morning I let them out early and was working in an out building. I heard squawking and I ran outside, there standing next to the field was a coywolf. He killed one and severely injured another but I was able to nurse it back to life and now she's doing fine. We found the leg band (we have 24 Black Stars) of the chicken the chicken the coywolf killed (we have 24 Black Stars) in the woods with teeth marks. We lost another to a hawk two months later

I know how you feel.
