I cant say much more than Michael did....
If you have the lower box 70% full you can pull a couple of those brood frames to put in the center of your upper box. I keep Mann Lake pf120's available, even if they are not filled yet, and drop a couple of those in as well...
IF, starting a new hive on all empty frames.. I try to make sure the frames are rubbed with wax, and use the pf120's (4.9mm cell size) to try to keep them straight. I use three of the pf120's in a ten frame box otherwise filled with foundation-less. I do not "under" super them, but also dont generally fuss with them much when the temps are low. In fact, I often pull the bottom box early (i use all mediums) and set the second box on the bottom board. I then cut the wax from the original bottom box, or place empty frames up top for them to fill to rotate my wax out..
I check them once a week when they are starting new foundation, and straighten comb IF needed. If they really get lopsided I cut out and make them restart. Overlyu fat combs just get skinned down with the hot knife.
Normally i dont have to touch anything... but then, when I had my "plastic" hives i had a start that built cross comb between the sheets of plastic.. I think they confused me as much as they were confused.. that was REALLY a mess to get going right.. hard to cut out plastic, has to be scraped.. THEN they just tried to rebuild what they had started. I ended up putting NEW frames in to get them going right. set them back a couple of weeks.
