A Cornish duck farm is celebrating an unusual birth after two ducklings hatched from one egg.

The twins, who are doing well, appeared from the same shell within minutes of each other on Thursday.

Roger Olver, from the Cornish Duck Company in St Austell, said it was very rare for two ducks born from the same egg to thrive.

He said the ducks, dubbed Romulus and Remus, will be spared the table and become pets.

He said: "One of them hatched first, just as the other was poking its beak out of the other side of the egg.

"It was a shock to say the least.

"They're looking pretty good, bearing in mind they were cooped up together in the same shell."
