To feed or not to feed right now?

I would refer you to @Dawn_SD, who is in the US (so better understanding your climate this time of year etc.) It depends on time frames of season & expected nectar flow etc. remaiming. Some colonies take longer than others to do what we expect of them.
Also this thread When should I add the super in Beekeeping Basics, on this forum. Perhaps it’s not a matter of feeding but, patience?

@Dawn_SD

how long would it “normally” take for bees that populate nicely 5 combs to build another one? (or is the term to use “to draw” another comb?)

Depends on the bees, the weather and food availability. In the best conditions, they might do it in a couple of days. But as it takes around 7lb of honey to build one 1lb of wax, if they are short of food, they will take a lot longer.
