"A supermarket has put electronic tags on chickens to stop them being stolen. The device, which is put on high value goods such as alcohol, has been placed on birds at a Sainsbury's store near Eastbourne, East Sussex. The supermarket is believed to have introduced the measure at its Hampden Park shop after a rise in the shoplifting of chickens."
