But we know that there is laying workers all the time in hive, I recall
research telling that several % of drones in normal hives were not from
queen, but from workers.
When queen is separated from part of hive / brood with excluder the
situation is abnormal for bees so I think its quite logical that these
laying workers use this situation for their benefit. And the other
workers are not so keen in removing the eggs as they do normally.
This is a survival mechanism for bees, how to pass on genes when
problems with queens.

Exactly the reasoning I have been using, but until now my result has
been different. I admit that I haven't researched throughoutly in this
but have read quite many articles about it during years. Many tell that
workers are capable of making egg, also diploid eggs. I have not found
study that would have eliminated this factor in 'egg moving' so I have
hard time believing that bees move eggs. I am happy to change my view
based on evidence.

I think this is good and I encourage others to try it as well. And share
the results in here please. I have to see if I can borrow a frame of
carniolan eggs to see the difference ( I have italians and buckfast)
But it will be a while before I can do it. After long winter willows are
just starting to bloom here, lakes opened last week from ice.
I use a lot of queenless starts. I see sometimes eggs in them (in queen
cups) , and I have always thought that it's the workers. There is no
frames with eggs moved into these starts.
