My son and his family lost 4 hens within an hour of each other and scattered at different areas out side the house.... head pulled off and left 10 feet from body.. 2 attacked from their rear side (vaginal ? area?) 1 several bites and all left dead...except the rooster who flew into a tree... I'm guessing a weasel or member of his family or maybe a possom??? but what or who would of killed all 4 within under an hour?? this happened shortly after them getting out of thier coop... and in the soutern Virginia mountains area.
