THIS beast of a lamb born at Cannon Hall Farm is the biggest it has ever seen.

She weighed in at 15lbs when she was born about a week ago during the farm's live lambing season, which is open to the public.

About 150 people watched every tentative moment of her birth and now she towers over the farm's other newborns.

The lamb is a Dutch zwartable breed and has been nicknamed 'Beefy' due to her size.
