Michael, What size equipment are you using? Are you saying the bees went from a 5 frame deep to eight frames in 11 days?
Usually bees will move up on their own in the brood box but you can move up an outside frame.
Are you using foundation?
Have you gone to the Mentor page to see if there is a local mentor who would be willing to help you?
Ok, so then you are all set.
Watch and see what happens next. We are currently on a nectar flow and bees are quite busy.
If the bees don't require the added space they won't use it.
Resist if you can...going into the hive too often. Lots can be determined by observation at the entrance :)
Hope this helps, Lee
