Food of the future: Therapeutic eggs! Perhaps geneticists and other scientists will raise genetically altered chickens to lay eggs with differing chemical compositions. Other chickens will be given a special diet. In the end, many things that could ail you may be cured by eating these medicinal eggs. Some general purpose eggs, for instance antibiotic eggs, you’ll be able to get from your local grocery store. Prescription eggs will most likely have to be purchased from a farmacy.
