Re: Do you think this colony has a Queen?
If photo #2 is all the comb that they have built after 2.5 months, then yes, I would say there is something amiss.
It sure looks from photo #2 that your TBH has an open screened bottom. If that is the case I suggest that you close it off. Simply screwing a board under the screen is one option if you don't have a closure board already.
I don't know exactly what the problem is. When you installed the bees were you offering syrup to this hive, and did they take it? When was the last time you saw eggs/larva?
