My top boxes look great - I now have 5 boxes on each hive and they are filling the 4th box, the bottom boxes don't have windows though.
What a great nectar flow - I was not planning on harvesting honey this year, but I may have to take the top boxes in order to get the hives down to a reasonable size for winter.
Here are videos of each box:
July 2 2018 - we returned from a week away horse camping in Roosevelt Nat'l Park to find Hive B's roof/quilt box on the ground! Must have been windy here. The top cloth was pulled back 1-3" on the SW corner and some bees were going in and out of the top box. Thankfully, it was plenty warm and the queen must not have left. I put the quilt box and roof back on!
July 4 - Mark helped me lift FOUR boxes on each hive as we added a box to the bottom of each hive because they were filling the bottom boxes. Hopefully, we did it in time and she won't swarm with half of her hive.
Got the smoker going, beautiful day out and around 10:30am, Mark and I lifted the 3 boxes on each hive and added a windowed box to the bottom.
I put some pollen patties on and kept the feeders on.
All looks good.
Here they are:

the light boxes are my feeder boxes, we use the white table to move the boxes over then place a new box down and replace the hive on top of the new box. It's slick and it's the perfect height.
This must have been a record setting day.
Suffice to say the bees are busy, though the bee population in my overwintered hive still seems slim in comparison to my package, but feeders were nearly empty on both hives so I topped them up.
I can still feel pollen patties under the top bar cloth so I did not open the hive to replace them.
The bees are always at my bird waterer by my house, despite the fact that I have supplied them with a bucket of water in the apiary.
