Concur, Both those pictures contain a Queen.
Where in Mich are you , Kindly add your location it helps for advise.
if you are south of Mt Pleasant , feeding would not be mandatory any more, If you are in the UP I would continue to feed. If adding only foundation or FL frames then some feed would help with build out.
Let them roll, IF you have 2 Queens, when you hit , 3 medium 8 frame boxes of bees you could split the hive in 2, or just let it ride.
If you split, I would take 4 frames from each box , from the same side , left or right, move to a new set of 3 boxes, center the bees, add 2 to each side , make sure each has a queen.
keep in mind a 2 queen hive will grow, fast and big, I have 1 queen hives get head high in a summer, on 8 frame, so hopefully you have some boxes, like 8-10.
Next time in pay close attention, and see if you really have 2 or seen 1 --2 times.
