This is all very interesting. Went through my hives yesterday. Hive 2's queen is laying a pretty pattern in the bottom box and the top box has 9 frames partly drawn out being filled with honey, NO idea what nectar they are finding except trees.
Hive 4's queen is laying in the top box, workers and a frame or 2 of drones and there are uncapped queen cups on the bottom of 2 frames, no egg in them. The bottom box is crammed but dusk was approaching and this is a fairly hot hive so I had to get out before I hurt a bee going into the crammed bottom box. They are a robbing hive as well. I was concerned that they might be overcrowded but at least 5 empty frames in the top box, the drawn out are being drawn as honeycomb, pretty white wax, and laid in.
I suspect she is planning a swarm and soon...
