>There was a very small amount of capped worker brood but the drone brood was far more numerous, totally dominating the faces of some frames.
First, a failing queen would lay a lot of drones. Second it's 24 days after the old queen is gone before the drones would have emerged. So for the next 24 days there would still be a lot of drone brood and the last of the worker brood would have emerged three days before that.
>We suspected that the queen (the 2nd of the season) may have been killed or seriously impaired.
Or seriously impared and then replaced.
> We did find her eventually and she looked perfect aside from the fact that she was wandering seemingly aimlessly on an outer frame with no visible attendants
Typical of a virgin queen. Give her two weeks and I'll bet you'll have a nicely laying queen.http://www.bushfarms.com/beesmath.htm
