Every year, the poultry industry kills up to 7 billion male chicks simply because they do not produce enough meat (or eggs) to justify raising them to adulthood.
While the female chicks are spared for egg laying, the male chicks are eliminated and disposed of by hatcheries through suffocation, maceration – a process that involves a conveyor belt and a giant blender – or other methods in a procedure known as male chick culling. The male chicks are generally killed soon after they hatch and shortly after their gender has been determined.
Now, a technology called TeraEgg developed in Israel by Novatrans, can determine whether the egg will hatch into a male or female chick before incubation, preventing the hatching of eggs containing male chicks.
TeraEgg, which recently completed its early testing phase, analyzes organic compounds to identify the gender and fertility of eggs before incubation through a non-invasive process that uses terahertz spectroscopy (electromagnetic waves). This technology is able to determine whether it is male, female, or infertile through the detection of gasses that leak from the pores of the egg within seconds, rather than allowing the chicken to hatch – a process that otherwise takes around three weeks.
In other words, TeraEgg detects gender and fertility in the chicken embryo development process, allowing hatcheries to remove male and infertile eggs before they enter incubation, so they can be re-purposed for human consumption rather than destroyed post-incubation.
