Emerging bees have the smell of the hive and their mother queen. Package bees come from several hives and a strange queen. Why should they act similar?
Package bees orient to what they consider the best home available. Usually it is the nearest one, but can be the next one if the pheremones from that one are stronger.
It's not that I doubt what you're saying it's just that I have never considered the possibility. I appreciate the information.
