It is not unusual to fill a deep in only four weeks with a mated queen. The first pictures in my Gallery at americasbeekeeper are of just that fast buildup from a swarm. A healthy hive should need supering in four to six weeks with a good flow on. Hives made at the April USFBG workshop are already getting honey supers. Those pictures are at 2010_Gallery on americasbeekeeper. In the March workshop everyone built a deep and a medium super. Several are already building and adding more supers.
