Drone Cell Mix with Worker Cells

[Mr. BeeKeeper2]

Yesterday I just checked in one of my hives I noticed that on frame that was filled with worker brood had one drone cell on it. I know that if you have Drone brood mixed in with Worker brood that mean you have a bad queen. So does that mean I have a bad queen?

Probably not - there are many possible reasons for one or a few cells containing drones in a comb otherwise containing mostly worker brood - most of them are not indicative of queen problems.
