Are these real cells or just cups? If they're empty and look like a little round ball with a nice round hole in the bottom they're cups. The bees build them continuously. If there are larva in the cells then they're trying to raise a new queen. Queen cells look like a peanut growing out of the side or bottom of the frame. Whatever it is, don't worry about it! Bees have been doing this for millions of years and have the situation pretty much in hand by now. If it's a supersedure they think they need a new queen for some reason; don't intervene. If it's swarm preparations, you can make a split with the old queen and let the old hive finish the cells. All the info is here on this site, just Search.
