Yesterday evening I saw a virgin queen in the observation hive for the first time since this craziness began.  She was running like a wild thing!

The reason soon became apparent.  The bees balled her! Note the condensation on the hive glass.  This point on the glass was considerably hotter than the surrounding surface.

This morning I found her on the bottom screen with a few workers attempting to move her carcass out.

Just a side note, After Swarm E occurred today.  I looked out and saw the queen on the landing board.  I attempted to catch her in a queen cage but failed.  We messed with the swarm a couple times and I think we saw the queen return to the hive.  The bees either dispersed or returned to the hive. It was quite small, maybe a cup and a half of bees.
