I think it is time to cut the apron strings and let them find their own forage!!
They don't need feed anymore!! They don't need the capped honey right now.
You probably won't want to harvest any of the capped honey in there since it has copious amounts of sugar water in there, so I'd recommend (if you can keep them safe)when they are capped taking a few of the oldest honey combs out, freezing them, and then replacing with empty bars. Then they can draw comb and fill it with real honey.
That way in the fall you can take extra honey (the real stuff) out and replace that with the capped "honey" from the freezer.
