A grandmother has defied the odds by cracking a box of 12 eggs and discovering that all of them had double yolks.
Carolyn Bannister, 65, was astonished to find that every egg in a dozen free-range box had two yolks.
What are the odds of 12 twin yolks in one box?
- The odds of any chicken egg having two yolks are one in a 1000
- The likelihood of having 12 double yolks in one box is therefore one in a quintillion - which is one followed by 18 zeroes
- It is also the equivalent of winning the lottery three times
Carolyn, who is a retired Ofsted inspector, bought the large eggs from her local Morrisons in Aldershot, Hampshire.
The grandmother-of-five then got her husband Ken to film the cracking of the last three eggs, which all contained two yolks.
Egg regulators The British Egg Information Service said double yolks tend to come from young hens whose hormone system has not fully developed.
