Just checking August 25

Since I was worried about the nuc I started feeding it sugar syrup in the hopes they would start working the third medium box. They have finally started, and they have finished off one bucket of syrup so far. Maybe they will have enough food for the winter.
In the not-so-happy hive I had moved 2 of the full frames of honey to the fourth box and moved 2 empty frames down into the third box to try and get them to start working the 4th box. That appears to be working, and they are now building comb in the other frames in the 4th box.
Since moving frames seems to work today I moved 2 frames between the 3rd and 4th boxes in the happy hive.
Both of the package hives appear to have totally filled the 3rd box with honey--before I messed with them so I think they'll have enough winter stores.
None of the hives appear to like the foundation I got from the honey exchange, or maybe it just seems that way since they are so slow drawing comb on it. Even with syrup the nuc is slow to draw out comb.
Now I need to start prepping for winter: Api Life and mouse guards to start, I think.

Today's inspection

I have been peeking occasionally into the hives to see if they need more space. They haven't needed more, but I have been worried about the nuc. The number of bees is so much less than the other hives. I decided to look and see is I could find the queen. The top box is still mostly empty, but they have started to draw comb in a couple of the middle frames. I started into the second box and the first four frames had honey. Finally I found a frame with eggs and capped brood and even a worker bee who was in the process of hatching. I'm still worried that I have an under-performing queen and maybe I should replace her, but since I have trouble finding her I am not confident that I can replace her.
I looked online and saw something about replacing a queen anytime between June 21 and September 21, but that was for a bee farm in Illinois. It may be too late in the season for Maine(?)
