An incredible rare 'double-faced' calf has been born on a farm - but she can only walk in circles. The farmer who owns the cow , Stan McCubbin, admitted he was stunned when he discovered the new arrival, and originally thought it was two twin calves lying together. The animal has four eyes, but can only blink two. She also has two noses. And while she can stand up on all fours, she struggles to walk and often ends up trotting around in circles before falling over. Both of her mouths also move at the same time.
