The brood comb is the beeswax structure of cells where the queen bee lays eggs.
During the summer season, a typical queen may lay 1500-2000 eggs per day, which results in 1500-2000 bees hatching after the three-week development period.
When a queen does not have enough brood comb to lay eggs, usually due to congestion from pollen or honey,[citation needed] the bee colony may be more prone to swarm.
[citation needed] The hexagonal prismatic cells for the brood comb vary in size.
The change in broodcomb color is due to the cocoon that remains inside the cell and also small soil and pollen particles that are tracked in by the bees over time.
