Three queens, caged, placed on a small scrap of wood, on top of a queen
excluder, covered with an empty super above a queenright hive - lasted
better than two weeks before being "called to report for duty". The bees
came up and tended to them (It even snowed the second day they were housed
this way - a late spring snow in Central New Jersey). Some attendants didn't
make it but all three queens were OK.
