(26 different artificial eggs. The artificial egg is the main development. Basically they take a chicken embryo (by cracking open a fertilized egg) and allow it to develop inside the artificial egg, and from which it can eventually be "hatched". Other methods for growing chickens from embryos outside their eggs have not had very high success rates.)
