I figure they build what they want and I leave them. After all I am new to beek and they have been doing it or their ancestors have been forever. This is in my Langs, I also have a TBH where they build ever frame. I look to see how the bees are doing, if they are building comb, fill it with stores and the queen is laying, and if there is any pest, SHB, moths, mites etc. If everthing looks ok I'm happy and I figure they are also. Good luck
