Eli5 when a hen lays eggs, what happens to all the eggs that would make a rooster?
In: Biology
Every time a hen lays an egg, it’s basically menstruating. Having its period. The eggs will not generally be fertilized. Most chickens are segregated, so that the roosters won’t mate with the hens.
When somebody wants to raise chicks, they’ll put the rooster(s) in with the hens so they’ll get busy. Then they let the hens sit on the eggs, which eventually hatch. Some of those chicks will be male, and if raised will become roosters.
In most factory farms, the boy chicks are killed early, because it’s not profitable to keep them. This is done after they hatch, as we can’t sex a chick before then. So to answer your question, they go the same way as the eggs that would make hens.
