I'm a new beek. I have 1 hive that I inherited from my father who recently passed away, and one captured swarm from that hive that seems to be doing well. Lately I've noticed the drones from the original hive being chased out by workers, sometimes as many as two or three workers on one drone. Everything I've read says that it's not unusual for drones to be evicted around the end of summer or early fall. Is it a bad sign that drones are being chased away at this time of year? I appreciate any input.
