  Do the hives seem healthy otherwise?  Have you eliminated mites as a cause?
Remember that the bees which have overwintered are old. The hive should be
brooding up, but little or no new brood has emerged yet. These old bees, when
they have a few good days of flight, burn themselves out quickly. I have seen
this often, just after the first nice weather (and bloom) of spring.
Sometimes there are so many dead bees, one would think of a pesticide hit,
but pesticide use would be very uncommon at this time of year in this area.
