Hot weather and they are thirsty

It has been very hot here so the bees have needed a lot of water.  They have started visiting the water station I provided for them.  I need to refill it every couple of days.

Today I went into #3 in order to remove the Apivar strips I put in 6 weeks ago.  Of course, I looked around the rest of the hive as well.
In the top box there was some capped and unripe honey.  I suspect that it is made mainly from the sugar syrup they have been fed.  There was some brood, and, surprisingly to me, some areas of drone cells.  

Drone cells in the center and capped honey around

Perhaps it is the unusual weather.  I did not see the queen, but I believe she is doing well because I saw very young (2-3 day old) larvae. 
Surprisingly because this is when drone production should have stopped.
There was also good pollen stores.

Conclusions:  #3 is doing well and I need to continue feeding.

They were hungry

 I looked into the hives today to see how the bees were doing with their sugar discs.  Olea's bees had not only eaten all the sugar, they were also eating the plate.  

The white crumbly stuff is chewed up paper.  There is no more sugar.

 The bees in #1 had finished all their sugar, so I put a disc in the Vivaldi box and they immediately started eating.

#2&3 had yet finished their first serving.
