broods

Broods serves as both noun and verb around the idea of offspring and anxious dwelling.

A brood is a group of young animals, especially birds hatched together: a brood of chicks.

By extension, it can refer humorously to someone's children: She arrived with her whole brood.

To brood is to sit on eggs to hatch them, or figuratively, to think anxiously about something for a long time: He brooded over the insult for days.

A brooding person dwells on dark thoughts; a brooding sky threatens storms.
