The arrival of four identical heifer calves in Norfolk is causing a sensation in the farming world.
The chances of heifer quads is a billion to one
Geneticists say the birth of Primrose, Daisy, Bluebell and Poppy beat odds of a billion to one.
"It's a one-off, isn't it? I have never seen it before and I haven't met anyone yet who has," said Geoff Brand, of Plantation Farm, Shotesham St Mary.
The calves' mother is a nine-year-old Hereford crossbred Simmental called Dash.
They were fathered by Mr Brand's top six-year-old pedigree Charloais stud bull, Lakenheath.
The beef producer said he planned to keep all four heifers, who were so weak when they were born they had to be nursed by him and his wife, Jean.
"It's still early days but maybe one day we will have a picture of four quads with four calves," he said.
