The 7 billion male chick problem — and the technology ending it
Approximately 7 billion male chicks are killed annually worldwide in the egg industry. Male laying-breed chicks cannot lay eggs and don't grow fast enough for meat production, making them economically worthless under conventional production logic. They are killed immediately after hatching, typically by maceration (grinding) or gassing. Even with the fastest, most welfare-positive killing methods, this represents an enormous scale of life termination that has motivated a global search for alternatives.
In-ovo sexing — determining egg sex before hatching and before nervous system development is complete — represents the most promising solution. Key technologies:
In-ovo sexing adds approximately 1-3 euro cents per egg — a small consumer price increase that effectively eliminates male chick culling. Consumer willingness to pay for this is high: surveys show 70%+ of EU consumers support paying this premium.
