A hen in Suffolk has laid an unusually large egg. The egg which has a circumference of 21cm (8.3 inches) was laid by a hen called Matilda who has only ever laid four eggs before. Despite the size of the egg it is not large enough to make it into the record books. The largest ever hens egg was a five-yolked egg measuring 31cm (12.2in) around by 22.8cm (9in) and weighing nearly 340g (12oz). It was laid by a Black Minorca hen in Lancashire in 1896.
