In a honeybee colony, the broodnest is the specific area within the honeycomb where the bees develop from eggs.12

Within the hive, the queen lays eggs in the cells of the honeycomb, typically one per cell. The bees maintain a precise, uniform temperature of approximately 93 °F (34 °C) within this area to ensure the proper development of the brood, regardless of external weather conditions.123

Regarding the organization of the hive, the broodnest is generally situated below the honey stores, which are typically kept toward the top of the combs. Pollen, which provides the essential proteins required for rearing young bees, is stored in cells surrounding the broodnest. As a colony grows during the spring, beekeepers may manipulate the hive to allow the queen to expand this egg-laying area, helping to manage the colony's population and prevent swarming.124
