Egg Industry Male Chick Culling and Alternatives

Approximately 7 billion male chicks are killed annually in the egg industry because they cannot lay eggs, typically by maceration or gassing, but in-ovo sexing technology offers a humane alternative.

Key Facts

An estimated 7 billion male chicks are killed globally each year in the egg industry
Maceration in a high-speed grinder and CO2 gassing are the two most common culling methods
Male chicks of laying breeds cannot be economically raised for meat due to their lean body type
In-ovo sexing technology can determine chick sex before hatching, eliminating the need to hatch and kill male chicks
Germany became the first country to ban male chick culling in 2022, requiring in-ovo sexing
France followed Germany in implementing an in-ovo sexing requirement in 2023
The technology adds approximately 2-3 cents per egg in cost, a modest premium for eliminating billions of deaths

Welfare Considerations

Male chick culling represents one of the largest sources of hidden animal death in food production. Whether day-old chicks experience suffering during maceration or gassing is debated, but the precautionary principle and scale of the practice argue strongly for adopting available alternatives. In-ovo sexing eliminates the welfare question entirely by identifying and discarding unfertilized eggs before neural development occurs. The technology exists, has been validated at commercial scale, and is cost-effective. The primary barrier to adoption is regulatory will and producer investment.

What You Can Do

Choose eggs labeled as in-ovo sexed or from producers that have eliminated male chick culling
Support legislation banning male chick culling in your country
Urge major egg producers and retailers to commit to in-ovo sexing adoption timelines
Reduce egg consumption or switch to plant-based egg alternatives
Support organizations campaigning for elimination of male chick culling
Raise awareness about this largely hidden practice in egg production
