One of the packages we installed around April 1 is in trouble. I noticed a few weeks ago that they were queenless, but at that time there were several queen cells on the upper sections of the frames. Now, those cells are gone, and I cannot find a queen. What I did find were several frames of spotty drone brood. There is no worker brood in the hive. I need to have a queen, but I am unsure how to get the bees to accept her at this point. My other hives are all starters as well. Two packages and Two nucs. (our overwintered hive was robbed out last week and is gone). The others are doing well, but I really do not havve much in the way of assets to borrow without hurting the buildup of the others. Any ideas?
