the last couple of days i have noticed a few drone flying into the hive. prior to this, i had only seen a couple of drones anywhere. the health of my hive seems to be good, so i am not worried about it. just curious.
is this when the hive tosses to drones out? do they kill them, or just banish them? are banished drones trying to return home? what else might the drones be doing outside the hive?
