Who was the seller?
I bought a nuc from an operation in NM. I would call it a medium strength hive. I received a nuc from a local Denver operation which turned out to be pretty weak, and 2 nucs from Apis Hives in Grand Junction, CO, which were excellent and are growing fast. There are my first four hives, so I understand the difficulty of not having the experience to judge the quality of a nuc.
