Opened the hive to look for queen cells per Dee's suggestion. Found more than 15 queen cells! Chose one and removed the rest, although a few fell into the bottom of the hive and as the girls were getting irritated, left them there. Also added another brood box, not sure they will need it, but I feel like it's better to give them room than not. Unfortunately, I don't have frames with drawn out comb to give them.
Also noticed that the bees are storing nectar where brood had been, will they fix that when there is a laying queen again?
