My two WBC hives stand in the same apiary, around 2m apart, facing the same way, with bees split* from the same original colony in May 2008.
Hive Alpha (the original) has a brood/half, and four supers. Two supers are full and capped, and the other two are about half full each.
Hive Beta has exactly the same layout. No supers are full, and there are fewer bees than in Alpha - at a guess, half the number - and the bees are smaller.
Now work that one out!
*I avoid the 'artificial swarm' term. It was more like 'incompetent jumbling.' See entry
