An Israeli company has made the question redundant by achieving something remarkable. 'SuperMeat' has grown chicken in a laboratory, and they now plan to expand the process to a 'commercial scale'. SuperMeat is holding test meals for customers in a small restaurant in the Israeli town of Ness Ziona. The restaurant is aptly called the 'Chicken'. Diners here can devour the laboratory-grown chicken, produced without using genetic engineering or antibiotics. 

The process involves cultivating cells taken from a fertilised chicken egg. Cell cultures are fed a plant-based liquid including proteins, fats, sugars, minerals and vitamins.
