Mostly drones? Usually it’s all drones or mostly workers…
As far as her appearance, I can’t see her that well and size varies a lot. I’ve seen plenty of large queens that were duds and small queens that were great.
Here is Huber’s description of a late mated queen:
“Drone laying queens are shaped differently
I should also, Sir, describe to you the remarkable manner in which the queens that lay only drone eggs deposit them sometimes in the cells. They do not always place them upon the lozenges forming the bottom of the cells, but often deposit them upon the lower side, two lines (11/64th in. or 4mm) from the mouth. The reason of this is that their belly is shorter than those of queens whose fecundation has not been retarded, their posterior extremity remains slender, while the first two rings next the corselet are extraordinarily enlarged: it results from this that, when they dispose themselves for laying, their anus cannot extend down to the lozenges at the bottom of the cells: the enlargement of the rings not permitting it; and consequently the eggs must remain attached to the part reached by the anus. The larvae proceeding from these spend their vermicular state in the same place, which proves that bees are not entrusted with the care of transporting the eggs of the queen, as had been presumed. But in this case they follow another plan; they lengthen the cells in which eggs are thus placed 2 lines beyond their opening. Note: This observation also teaches us that the eggs of bees need not be fixed by one end at the bottom of the cells in order to be fertile.”–Francis Huber, New Observations On Bees, Volume I, 3rd Letter, 21 August 1791
