Call me a cynical old so-and-so if you like (I've just turned 47 and I'm a bit grumpy as a result), but I detect the faintest whiff of 'stunt' with this one. In my previous life as an evening paper journalist I'd have treble-checked it.
What made me suspicious was the fact that the story on the BBC website had a link to the farm's range of delicious sausages! The words 'plug' and 'free' sprang to mind.
Having said that, I wish I'd thought of it.
