>Murray might possibly have one showing a new queen of a totally different
race (same as neighbour) 

According to evolutionary biology, there is no purpose for which a colony
would steal an egg from its neighbor. The colony exists as a family and to
continue that family. 

They raise the eggs of their queen and if the queen perishes, why would they
steal another queen's egg? This makes no sense at all from an evolutionary
perspective (which is only an explanation, of course, but a good one).

Stealing eggs would only serve to perpetuate another family's line, which
they would have no real interest in doing. The colony labors to continue
raising the young of their queen, their own kin.

Furthermore, I do not know if a bee can even hold an egg in its mandibles
without ruining it. Unless someone has seen this, it's all just guessing. I
would suppose that if this were possible, someone would have seen it by now.
