Animal rights group PETA wants a "tombstone memorial" dedicated to the chickens injured and killed when crates of live birds fell off a truck onto the doorstep of a KFC outlet.

Dozens of chickens landed outside the KFC at the corner of Gisborne Road and Bennet Street in Bacchus Marsh on Tuesday at 2pm after coming loose from the back of a truck.

A vegan passerby captured footage of the incident, which showed injured and dead birds being crammed back into the large yellow baskets. Feathers were also strewn all over the road.

A crowd of people can be seen flipping an upturned cage filled with pellets of live birds, while others gather up stunned chickens, many with bald patches that have come free onto the street.
