Definition
A mother hen is a hen that is actively caring for her chicks 🐥. More broadly, it describes someone (not just a hen!) who is excessively caring, protective, or even a little overbearing. Think of it as the friend who always makes sure everyone is okay, sometimes to the point of being annoying. Like, "Did you bring a jacket? Are you sure you have enough snacks?" The metaphor applies to anyone with strong nurturing instincts.
