SOOS has managed to do the impossible and has developed a technology that changes the sex of chick fetuses in-utero, avoiding the waste of billions of male chicks (which have no use in the egg market) and thus saving capital for the entire industry.
Even more importantly, SOOS has accomplished this without any medical invasiveness or cause of suffering as well as having no impact on the genetic code of the chicks. They achieve this effect utilizing sound waves, a technology already known for it's extensive applications in medicine.
