Welfare of Animals in Egg Hatchery Operations

Commercial egg hatcheries kill 6-7 billion male chicks annually worldwide within hours of hatching as an economically unavoidable byproduct of the egg industry.

Key Facts

Male chicks of egg-laying breeds cannot produce eggs and are too small for meat production
Maceration (high-speed shredding) and gassing with CO2 are the two most common killing methods
In-ovo sexing technology can identify male eggs before hatching, eliminating the welfare problem
Germany and France have mandated in-ovo sexing adoption
The technology adds approximately 1-2 cents per egg to production costs

Welfare Considerations

Male chick culling is one of the most straightforward large-scale animal welfare problems with a known technological solution. In-ovo sexing identifies the sex of an egg before the chick develops to the point of sentience, allowing male eggs to be diverted to other uses rather than hatching live chicks who are immediately killed. The technology is commercially available and has been mandated in leading European countries. Consumer and corporate pressure can accelerate its adoption globally.

What You Can Do

Choose eggs labeled as produced with in-ovo sexing technology where available
Pressure egg producers and retailers to adopt in-ovo sexing timelines
Advocate for government mandates for in-ovo sexing adoption in your country
Reduce egg consumption as a direct welfare intervention given the scale of male chick culling
