How do chickens “sync” their eggs?

673 views

I’ve seen friends post photos of chickens who disappeared and come back with a clutch of chicks. Assuming one chicken, laying one egg a day, how does a broody mom come back having hatched 3-5+ in a given cycle? Do other mothers sometimes contribute to a clutch, too?

Do they hatch progressively or sync up a bit, does the mother hen manage the eggs to get them all the same “amount” of incubation as to have them hatch out nearly the same time?

A hen can lay a clutch (5-7) over a few days. They rotate the eggs in and out of the center to evenly heat them, so slow/quicken the development.
