While doing some research on pheromones I came across a piece of research being done in either Australia or New Zealand on laying workers in a queenright hive. What I remember is that it was assumed that 6% of all eggs laid in a colony are laid by workers but are eaten by the "egg police." The investigators were way beyond "Does it happen?" They were looking for the clues (Pheromones) that the police use to find these eggs.
