well don't jump to conclusions, I had one that was suspected of a laying worker, a month after I put them up couldn't find a queen or eggs, just what looked like drone cells, so I dumped them out. guess what there was a queen in there ,, so its easy to find her if you dump them on a sheet or tarp. not that I recomend that, point is don't jump to conclusions, sometimes the queen just takes a while. and she can hide very well. If you give them a frame of brood and eggs, if there is no queen it takes 48hrs to ssee a queen cell. if not you likely have a queen.
