Eli5 when a hen lays eggs, what happens to all the eggs that would make a rooster?
In: Biology
What others said; for the egg laying kind, the chick roosters are shredded or gassed.
Nowadays there are ways to identify between male and female while still in the egg. Slowly this is gaining traction. Legislation to forbid such culling would go a long way.
