Slow Building Hive

[YpsiBee2015]

So, I have a have that I got in the form of a nuc that was already installed in my 8 frame deep.

It was started at the supplier/farm....lets says....May 1st

May 20th: I got them, and opened them up a few days after placing them at my house, and found a queen cell (QCs).
June 2nd: two queen cells
June 9th: Found the queen that hatched, no more QCs
June 22nd: Found the queen again, but there is another capped queen cell again....

The whole hive was all on about 4-5 frames when I got them. A month or so later, they are still on just about the same amount of frames.
There is little brood, and I am worried that my current workers will start dying with out any new bees to replace them. I'm kinda in a pickle here. This is my only hive, so I can't pull a brood frame from another one of my hives.... Should I be worried about this new QC. Also, is it normal for a 12ish day old queen to not really be laying?

Thanks!!

The queen which hatched and was seen on June 9th, should be laying. It may have taken her a while to get cranked up. You should be seeing lots of eggs and young larvae now. As for the QC you see now...Is it possible that this is one of the QC's that was present before? The bees may not have torn it down yet. It may not have had a viable larvae inside. Check to see if it is still sealed. Sometimes, a cell looks sealed, but there is a hole in the back of it.

If it is a new sealed QC, it was either layed by a laying worker (they are trying to raise a queen any way they can) or by your queen (more likely). Just one or a few queen cells would suggest supercedure, and not swarming. More than likely, this is an old cell, or a cell they started before that new queen pheremone kicked in good. Look in there tomorrow. If you have a lot of larvae and eggs, you should be alright. In that case, if the queen is present and is laying good, I would probably cut out the one queen cell and see if they still want to replace her.
