As a beekeeping advicer I have had many talks with beekeepers about bees 
moving eggs.

This far I have been very negative on the idea.

Eggs emerging in honey boxes above excluder are not evidence.

1. most cases beekeepers missed an second queen.
2. we know that thetylokoidia (spelling most likely wrong) exist in all 
races, so small percentage of workers can make viable diploid eggs in 
all hives. African bees are better in this than others.

Peters original post from 50's was first time I started to think that 
bees could move eggs. The fact that eggs were seen in mandibles did not 
impress, could also be that that egg is going to be eaten soon.

But the fact that yellow bees were born in dark bee hive with caged 
yellow queen is a proof, if this report is true.

Any trial of this must be done in a way that the eggs from queen can be 
identified separate from eggs of workers.
If this is not done there is no evidence.

Randy presented reports by Winston showing much more eggs emerging in 
queen cells in african hives, when there was no access by queen. This 
sounds very much like workers making viable eggs.

 From memory I recall a study that in some african races ( capensis) up 
to 20 % of bees can produce diploid eggs. in European races only 0,15 - 
2 % did the same, but the trait exits, so we can not forget it.
