Ben Oldroyd has sent me a copy of his work on the drones above the excluder.
The reference for anyone wanting to follow this up is:-
Nature Vol 371 27 October, 1994 page 749. It appears in the scientific
correspondence section. The title is "Anarchy in the beehive - Benjamin P.
Oldroyd, Adam J. Smolenski, Jean-Marie Comuet and Ross H. Crozier"
By the way, the queen had mated with at least 12 drones.
