Chick culling

Chick culling is the standard industrial practice of killing neonatal male chicks within the commercial egg industry shortly after they hatch. While consumers rarely see this process, it occurs at the hatchery level before birds are sent to farms. Because male chicks of egg-laying breeds cannot produce eggs and do not grow large or fast enough to be profitable for meat production, they are considered a byproduct of the global food system rather than a viable agricultural commodity.

The process begins immediately after hatching when workers, known as sexers, manually sort chicks by gender. Once identified, male chicks are typically destroyed using one of two primary methods: high-speed maceration or carbon dioxide gas inhalation. Maceration involves a mechanical grinder that kills the birds instantly, while gas stunning leads to unconsciousness followed by death. These methods are designed for high-volume efficiency, processing millions of birds annually to maintain the specialized separation between the egg and broiler meat industries.

For the conscious consumer, chick culling represents a significant ethical tension in egg consumption, even within organic or free-range systems. While some countries are beginning to mandate in-ovo sexing technology—which identifies the sex of an embryo before it develops sensitivity—this technology is not yet universal. Understanding this practice allows shoppers to look for specific certifications or alternative plant-based products if they wish to avoid supporting the systemic disposal of male animals in the traditional poultry supply chain.
