Still have two queens

I took a look into both the old and new hive today.

Top queen

Bottom queen

I spotted both queens in the new hive.  The bottom queen was much more active and would quickly run onto the shaded (under) side of the frame.  There was still only a small area of brood in the top box.  Honey production continues slowly.
I spoke to James, the local beekeeper from whom I had borrowed the nuc.  The swarm I had given him was queenless, or the queen did not returned from her mating flight, so no colony developed.  He suggested making a second entrance on top.  I'm not going to do this and will just see how things develop. 
There was lots of brood in the bottom box.   I thought the stored pollen was pretty.

The comb on the plastic frames in the nuc I got from Jeremy had an uneven surface and irregularities.  I sort of expected the bees to remold it, but they haven't.  Perhaps they will in the spring when they start making more comb.

I only looked in the supers of the old hive to check for honey- there isn't much.  I replaced three frames of foundation with frames with drawn comb.
I took notice of a difference between the two hives.  The new hive has considerably less propolis.  It is difficult to pry apart the boxes and frames in the old hive and my tool gets very sticky.  I hardly even need my tool while inspecting the new hive.  Most sources say that Carniolans are heavy propolis producers and my extensive experience bears that out.

Sugar shake on new hive

It had been cold and overcast yesterday, but today was clear and when it warmed up in the afternoon, I went into the new hive.

First, however, I placed the entrance reducer in the old hive.  Jeremy Rose, as do others, advises placing entrance reducers this month.  Since the main honey flow is over, robbing will start happening as colonies are storing up for winter. 
The returning foraging bees were initially confused.

Then, into the new hive, where I placed an entrance reducer, as well.  I spotted the upper queen.  There was also a patch of capped brood and larva, about 3.5 cm on two frames.  Honey production, although ~90% nectar continues and seems to have increased.  Eric Mussen, the UC Davis entomologist, thinks that the honey is being made from the bees in the lower brood box.  Bees usually store honey above the brood, and so they are just going through the middle box and storing honey on top.  Furthermore, he suggests that the nurse bees from the top box were attracted to the bottom brood box.  But since I saw brood on top today, I know she's laying and there are some nurse bees.  Maybe the honey makers from below and the baby makers on top are competing for space.  I think I'll ask Tom Seeley.
In the bottom brood box, I spotted the queen and lots of brood.  I did a sugar shake count: 11 mites in about 250 bees, 4.4 mites/100 bees, and acceptable number.  I had been prepared to treat with formic acid (Mite-away quick strips) but will now hold off.  I will repeat sugar shake test in a couple of weeks.
