we have these huge fucking vultures out here i dont think there hawks,
the vultures have like a 5-6 foot wingspan atleast
the plywood pens walls are about 5 foot high
pisses me off
They'd just sit around and wait for the duck to die, then eat.
Maybe on rare occasion would they gang up and peck at something, but a live hearth duck can drive them away, and fly...ducks are faster flyers than vultures. Vultures need space, and are ungainly.
Something else could have gotten to the duck.
