Does a hen get up to let the eggs hatch?

[CurvyCoop]

Newbie chicken question

Does a brooding hen get up to let the eggs hatch under her or does she stay seated on the nest and only gets up when everything has hatched?
Mainly asking because I'm wondering if you can see eggs hatch under a broody the same way (or at least close enough) as in an incubator/hatcher.

No she sits while they hatch.

She sits but it's not like she's squishing them. Broody hens sit with their feathers all fluffed out so there's space under there for the chicks to hatch out in.
Listen for peeping!
