Is this one full super per colony? Capped?
Entirely your choice, really.
Hedge your bets if possible.
Remove and replace with feed or perhaps remove some frames and replace with drawn comb if season is still progessing in a collecting mood (thinking here that you probably don't have any drawn frames?).
Remove some frames and feed.
Remove all and feed.
As to hedging your bets. If you have any drawn comb to put on now, you could store your harvest until you are sure the winter food has been accepted by the bees and fully converted to sugar-honey. You can easily mark those proper honey frames with a drawing pin or similar. Replace those stored frames, if plans go awry.
You certainly need to assess your varroah treatment, within this time-scale as well.
So, more than a couple of options and your final choice.
I am probably near to Hivemaker in thinking - take it off and treat. But it is the small print of the situation we have not read that may make your choice different.
For instance: how do you anticipate extraction? If it involves destroying the drawn comb, forget it in your first year and play safe! Work out the 'what ifs' and always work with the safe options in your first couple of years, is my advice.
You are a tad further north than Onge, so the season may be a lot different on the other side of the country.
Any local beeks to enquire to? Local BKA? Now a week into September......
