Just heard a commotion out in the duck yard. Looked out the window to see my one laying hen attacking something on the ground with three other ducks attacking the back of her head as she was attacking the "critter". Ran out to the duck pen to see what it was. They scattered when I came out. There is a stick laying on the ground where the commotion took place. ??? Why in the heck would they attack a 4 inches stick? I see no evidence of anything else in the area, but they were sure going at that stick (?). All ducks are fine....even the back of my hens head.
