Every year, approximately 350 million male chicks are killed by the U.S. egg industry because they do not lay eggs, leading to new technologies that identify male embryos.
This month, a new system started operating in Iowa, where a machine can separate eggs by sex, allowing for ethically produced eggs that consumers can feel good about.
Maceration is a controversial method of culling male chicks, which the industry claims is humane due to the instantaneous death it causes, yet its visual impact remains unsettling.
The culling stems from a long-standing poultry industry practice of breeding chickens specifically for meat or eggs, thus rendering male chicks from egg-laying breeds disposable.
