It's a bizarre story that is sure to reinvigorate the age old philosophical question of 'What came first: the chicken or the egg?': a chick in Sri Lanka has been born live, without an egg. The oddball event, which has been confirmed by certified veterinary officers in the area, is actually more of a biological mystery than a philosophical one. Quite simply, birds are supposed to lay eggs. In fact, no bird species has ever been discovered which gives birth to live young. Could this Sri Lankan hen therefore be the first bird ever to do so?
