What is bee brood? This is the next generation of bees – it is the part of the hive that produces bees constantly to replenish and grow the hive population.
Bees produce drones to spread the genes of the hive to other hives. Drones are big!! Natural worker cells are 4.5 mm (Apis mellifera capensis) to a maximum of about 5.1 mm for larger races.
