well i walked out onto the back porch to close the gate that the wind had blowen open, and what do i see, the ducks useing the automatic dog feeder. i think that we startled each other, because they just looked up at me as if to say "what, what do you want". i just ahut the gate and was heading back inside and i heard them start at it again. it was pretty comical to see. i thought that duck had a brain the size of a walnut with very limited learning ability, but i was wrong. they had to figure out a complex way of getting to that food.
