Things That Go Clank In the Night

In this hot weather we have been having I have my bedroom window open wide at night. The thing is, the friendly farmer has plonked this aluminium calf feeder in the field just outside. The calves find their way inside to eat their supplement but of course the mother cows cannot which is the object of the exercise. The cows feel they are being short changed and bash and bang away trying to find a way in. At night the clang clang of the feeder keeps me awake! I wish the powers that be had designed this contraption to at least make the sound of Trinidadian kettle drums - the cows would be dancing and swaying to the music and so would I!
