i don't know, but it ended up being a three deep brood box hive and gave me two full supers of honey. that from a package. later, they must have booted a queen out. i found one on the front porch but there was one still laying inside.
no, it was my fault for not realizing that i'd lost the queen over the winter. we had some really nasty weather late, and i didn't check. by the time i realized i'd lost her, the numbers were way down. i attempted to requeen, but it didn't take. the last of the bees from that hive were combined with one of the new packages and that seemed to go ok.
i don't have enough experience to give you any advice on letting them go, or requeening. i tend to lean toward MBs way especially this early in the year. requeening is a bit of a crap shoot, but if they pick their own queen, your odds of keeping her are better i think. it just takes longer for her to get up and going.
