I have three hives. On my strongest hive the bees are going like gangbusters. I have stacked 6 supers and they have filled them all. I am now out of empty supers and frames. Can I move an empty super from a weaker hive (one that had swarmed earlier) onto the strong hive?

Normally I would just extract, but I am not ready to do so yet. Would this be a no-no?
