Bob Harrison asks why anyone should want to super a swarm on the first day.
The reason is a quick super of honey if there is a flow.  If the swarm is
hived on foundation and there is a QE then a super of drawn comb the bees
will have no brood to feed for 3 days or more.  Some of them will be drawing
comb for the queen to lay in and she will soon be laying as fast as they can
draw.  In the meantime there will be thousands of bees with nothing to do but
forage and nowhere to put the nectar than the super you have thoughtfully
provided.   This only works if there is a flow.
