Warre hive is settled

Bees have settled in the Warre hive. They all moved to the top hive in the morning and started working on the comb strips I set up for them.
Even the hive I transferred bees from is still showing activity, although much less than other hives.
This is an experiment in the power of nature.
We have 4 hives in the yard.
The Warre, that has no comb but strong colony with a queen transferred into it. That would be like if bees settled new tree hollow in the wild.
The second hive is full of comb with brood, pollen and honey, but very few bees left. We hope that they will be able to raise new queen. This hive has least chance of survival.
Third hive is a control, new colony installed at the same time as the Warre. I just added a super to it to give them room to grow and to prevent swarming.
The fourth hive is a strong colony we started last year. They are in full swing collecting nectar flow.
