Lashing out ... farm worker kicks turkey in horrifying footage and, right, boss Matthews

The film released by animal rights supporters, is said to have been secretly shot by an investigator at one of the millionaire’s farms last week.

It shows a man in overalls delivering EIGHT separate kicks to turkeys in a shed at Wreningham, Norfolk.

Last year a film showed two other workers for Matthews — catchphrase "It’s bootiful" — playing ‘baseball’ using live birds on another farm.

The latest video is a new embarrassment to Matthews bosses, who claim they do not tolerate abuse of poultry. An RSPCA spokeswoman said she expected the charity would investigate the footage.
