The net gain in my colonies, the last couple of weeks, has been zilch, especially if the bees are brooding heavily. A lot are needing to feed colonies recently. Looks the same this week. That does not unduly worry me, as long as stores are OK.
Your local conditions must be better than a lot if they are laying down much stores, so I would think you need to make a local decision on local observation. One day's activity will not make a great deal of difference. Pollen is usually stored in the brood. I am doubting you need extra space at this time, but you may. Again I have only left a nearly empty super of drawn comb on one colony which is still too large for a 14 x12 brood box.
So I would say look, before you just do anything, and make you own decision based on what you find.
