I have what was a queenless hive; I had taken a frame of eggs/larvae/brood from another hive and placed in this hive to let the bees make a queen a few weeks ago. All looked good - they had made 4 queen cells so I had anticipated things getting back to normal. I checked the hive a couple of weeks ago - no eggs or brood, no sign of a queen (all of the queen cells were open; only the edges of them remained). Just to be on the safe side, I put another frame with eggs/larvae/brood in this hive about 8 days ago, and expected to see some queen cells in the works when I checked it today, but there were not any. Nor are there any eggs or brood on any other frames. If the hive is queenless wouldn't they try to make a queen with any available eggs/larvae? If the queen is there wouldn't she begin laying eggs fairly soon, since the comb is already there? Any suggestions on what I should do next?
