put them just outside the brood nest. You dont want to split the nest
what is that?
You shoud use langstroth too as super. Then you lift the capped and uncapped honey frame to there and extract when it is time. 4 capped langstroth frame = 10 kh honey.
Allways give new empty combs between honey and brood.
Give more space to queen lifting honey frames up and foundations to be drawn.
You hive sounds very good. 70 kg honey to be extracted!
