Re: nuc hived in 10 frame with top entrance
It sounds as though one hive was recently moved over from a smaller nuc, and the other was overwintered in its current hive body. Is that correct? If so, its not surprising that they have different amount of traffic at this point.
There are many beekeepers that would not give a new hived nuc excessive room. If you moved this nuc into a single deep, you could wait to add another box until they have built out 8 frames in the deep. Similarly, wait to add the second medium until they have mostly built out the first medium.
