I thought "usually" once there was honey surrounding the brood the queen doesn't usually move up into the supers.
Bees tend to keep the brood area compact
I agree with them filling if they have excess. When did you put your super on? When did the flow start? What's the weather been like? Hot and dry or cool and wet?
My now two plus year old (April 2011) double deep colony produced me three supers and began making bur comb between supers
They usually make burr when the hive is full of honey. Very normal.
They filled a super and when I went back to see if it was capped, they had moved it down
The colony has been too small/ hive too cold. That is why they concentrated the store around brood.
