A well-informed source from the sets of Amitabh Bachchan's quiz show Kaun Banega Crorepati 6 chirps to reveal that a few pigeons have been creating trouble for Big B. The birds perch themselves at least over 30 feet above the hot seat in the sets at Film City. They wing themselves in via an opening from the roof of the sets. And they have created their own hot seat right above Big B and the contestant. Their chirping often proves a distraction on the pin drop silence sets just before shooting commences. As a result two to three security guards have been employed only to shoo the birds away.
