the bees will always find their own home and if not, the bees from the neighbor hive will quickly dispell them until they find the right one
Unless the field bee is coming in with
nectar, then the guard bees will say come on in friend you brought food! (same as me with my neighbors!)
Drifting can be a problem with hives in a row. The end hives in your rows will usually get stronger because of wind. I'll rotate my end hives a couple times a year to middle spots to keep things equal. Swapping hive positions is a neat trick for swarm prevention, boosting a weak hive or getting a hive ready to requeen.
