How is hive #2 doing?

I'm glad you asked that question.  I opened #2 today because I was wondering myself.
There were some bees in the top box and one small area with nectar, but no new comb.
The bottom box seems filled with bees.  There still is no new comb on the side frames.  I was happy to see 4 frames with both sides filled with brood and a grapefruit-sized patch of capped brood on a 5th frame.  The queen was not seen today.
It looks like hive #2 is thriving, so I will not replace the queen.  So, unless things change or I decide to populate Olea's hive with the split, hive #3 is back.
