I installed my new package of bees on April 3rd. I released the queen on April 5th to avoid them drawing comb on the cage. I checked the hive on April 9 and did not see any eggs (as a first time keeper, I could have easily missed them). They were drawing on 3 frames (2 were about 1/3 drawn and 1 about 1/4 drawn) at the time. I didn't see/really look for the queen. I just closed it up and let them be. I checked on the hive yesterday (April 14) and they have 3 frames mostly drawn and working on 4th and 5th. I had one frame of larvae. I also noticed that they had made what appear to be queen cups in random locations. A couple on the bottom of a frame, one in the middle, and one near the edge. I looked inside and didn't see eggs or larvae. Should I be concerned about these or is it normal for them to make these?
