The current practice of gassing billions of male chicks within a day of hatching because they cannot lay eggs could be stopped thanks to a new embryo gender test. Globally some 3.2 billion cockerels are killed within hours of breaking free of their eggs each year. Now Dutch scientists have developed a simple test that identifies the sex of chicken embryos within eggs, meaning males could be terminated long before hatching.
