Local feral survivors in eight frame medium boxes.
Yes, I think that's enough for the moment. They need some stores and pollen close and they can rearrange things some to suit them, but if both boxes are full of honey then there's nowhere to raise brood. I wouldn't worry if they are in the bottom box or the top box as long as they are doing well and there's healthy brood and a little extra room for the brood nest to expand. Another thing you can do if the brood nest is small and surounded by capped honey, is just uncap the honey on each side of the brood so the bees will move it. Bees are reluctant to uncap honey to move it, but they quite quickly move it if it's uncapped and in the way. Again, though, there has to be somewhere to move it to.
