Are you seeing eggs, open brood, queen? If not, you may need a queen. Is there a flow on? If not, keep feeding.

I'm at the same pace as yourself. Nucs 30days old in the 10frme box. Mine built it out pretty quick and the nectar was coming in so much i too had to stop feeding just so they wouldnt pack out ALL the comb with nectar. After a couple weeks i did rearrange the outside bars to get them to build out more on some of the empty ones. That helped a lil as they seem to like building out 2 and 9 so i switched the 1 with the 2 and the 9 with the 10. I have a super on that they have to build out but they seem to be ignoring it for the most part or they are just really slow to start. I did observe them hanging on the frames like they do when their building comb but didnt see a lot. Saw lots of brood, larva and actually saw both queens for the first time this weekend so I just closed it up and called it a day. Gonna leave em alone for 2 weeks now and see if they've built anymore. You may try switching some bars on the outside to see if that'll ramp up their building. If you feel real brave and now thats its warmed up quite a bit you can try sticking an empty frame amongst the brood area and i'll betcha they start building that one out REAL quick.
