Questions this hub answers
- Are cage-free eggs cruelty-free?
- Cage-free removes the cage, not the crowding. Birds are still typically stocked at around nine per square metre indoors, debeaked, bred for yields of roughly 300 eggs a year, and slaughtered at 72–80 weeks.
- What happens to male chicks in the egg industry?
- Because they cannot lay and are not bred for meat, male chicks of laying breeds are killed on their first day, historically by maceration or gassing. In-ovo sexing now avoids this in parts of Europe.
