Gentlepeople:
     When I inspected a hive this past weekend I found it weak, with
     little or not foraging activity.  Inside I found little worker
     brood but an entire frame of solid drone brood.  It is obvious
     that the queen is a drone layer and needs to be replaced.  A
     replacement is on order and will arrive this week.
 
     This is my first experience with replacing a drone layer.  How
     should I proceed?
 
     Should I remove the "old" queen several days before I install
     the new one?  Should I add a frame or two of worker brood at
     the time of installation?
 
     Help?!
