If you are doing the queen-test, how long you have to wait before
checking back on the hive?  Also, if they have NOT created any
queen-cells, should you leave this frame in the hive or return it to its
old hive?  Will the bees in the recieving hive accept and care for the
larvae or will they kill them since they aren't from their queen?
 
I'm trying this test on a hive that I suspect has a virgin queen.  I
have empty queen cells but no eggs yet.
