In all my experience of major quantities of eggs in a super, the queen was in there and it was my fault (except one damaged excluder). Like last week putting a small excluder on as I had run out of the proper size (wbc vs national in the UK). The recent posts mentioned small quantities of brood. So, I cannot imagine a queen either sticking her nether parts through an excluder over a bee space and up to a cell on the lower edge of a comb or crossing over to lay just 2 eggs in queen cells. Nor can I imagine a worker laying a diploid egg in just queen cells. But moving eggs around does seem a likely thing. -- James Kilty
