I have a special problem with 4 of my 30 hives.
All my queens had startet to lay eggs in the early spring (end of
feb.). Than after i moved all of my hives to another place (in middle
of march) it seemed that i lost 4 queens; there was no eggs in
the hives and som time later there slip drones out of the worker
cells and there was also more than one egg/cell, also on the
cellwalls. I thougt i just lost my queens and a worker bee started to
lay eggs, or maybe a new young queen.
Next time i would ally the wrong hives with som healthy i noticed
some (regular, the old ones) queens in three of the 4 hives and they allready lay eggs TOTALY
NORMAL (one egg/cell on the cellground), so i think the queens are
working again. Until now tehre are only open breed so i dont know the
result of the "new" eggs.
 
Do someone have experience with coincidence like this or a idea what
the cause for a temporally infertility could bee?
 
For me it`s a mystery.
