Hey Deb.
I am betting that you have a virgin in there running around. From the time a new queen emerges to the time you will find evidence of a queen could easily be 3 weeks.
Which other hive do you have capped queen cells in?
Instead of transferring just a cell, you would be better off transferring the whole frame so as not to damage the cell.
If you lived closer I would just pop down and check it out for you. Are the bees calm and gentle, or are they "roaring" and upset when you inspect them? If they are bringing in pollen and all "seems" well, it probably is.
