Why Beekeepers Remove Spare Queen Cells

You might think this guy is hurting the bees by crushing those eggs, but that's not the case. You see, the hive raises multiple future queens at once for emergency replacement in case the main one dies or goes missing. But if those new queens hatch while the old queen is still around, a war breaks out. Because the hive splits into two groups with each side backing its own queen, and they'll literally fight to the death. So the beekeeper has to step in, either destroying the spare queen cells or marking the new queen and setting her aside to start another colony.
