Bottom box finds and lack of findings

When I went into the bottom box I expected to find some sign of the queen laying, but all I found was empty brood cells, a couple of queen cells and some stores of honey.

At least two of the queen cells produced queens. Not sure if that is where my queen came from and if she was a virgin queen so that is why I'm not seeing any signs of laying?

I have a call into the supplier to see what his advise is.

The hive seemed calm so I'm just not sure. If they were really hot I would KNOW that the queen didn't make it.
