I am a new beekeeper in northern NJ. After receiving my first nuc, I put the five frames of the nuc in the middle of the super. since that time, the bees have become active and thriving, and now honey is dripping down from the combs. But the hive has not grown: it still consists of the five starter frames. Why haven't the bees spread to the other five frames in the super? Why have they not moved upwards to establish comb in the super above? Also, I have not found the queen. So it would be helpful to have input on how I can determine whether I actually have a queen or not. Some pictures follow.
