How do I get my bees to start a new super?

I have two langstroth and and one top bar hive. All three have new packages of bees this year. I fed them to start and now they are not on feed. Plenty of natural feed now on my farm which is chemical free. We have a pond for water. They are right by my orchard.

They are doing great and there are tons of bees in each box. I have a an extra box on the two langstroth so I could have the feeders on top. I added bars to the boxes and added bars to the top bar but the bees are not starting any comb on them. What do I need to do to get them started on the new boxes? I want them to have plenty of honey for winter and have plenty of brood.

Thoughts?

We only use Langstroth hives, so I'll address only that part... We put a new box on, if the previous box is so full that the bees can't all fit into it when the field bees come home at night. They'll form a clump just outside the entrance. Then, when they get more space, they'll get right to work on it. We've been at this for 40 years, so we have oodles of previously drawn comb ready to go onto hives that need space. If we put non-drawn frames, we use foundation in the frames.

how long ago did you install the packages? what size were the packages? where were the packages created? what did you feed? is there pollen going into the hives?

If you have a langstroth, and the bees only fill 1 deep, you should only have one new box on top of it. If they fill 2 boxes you should only have a third on it, etc. As the colony grows they will eventually move into it and start using it. Don't worry I was impatient for it to happen as well... I had some fresh foundation and they were doing everything but drawing it out. As the colony got stronger they got to work and built it out. Also depends on nectar and pollen available.
