Two-headed calf -'One in 400 million'

A calf born on a small farm in Baker County, Florida with two heads has been dubbed a 'one in 400 million' animal - but is unlikely to live for long. Vets have said there is nothing they can do to keep calf (Annabel) alive for long. It is believed the calf was born with a condition called polycephaly - where an embryo begins to split into twins, but stops.
