Besides the obvious (one's a worker and the other is an old or injured queen), what's the difference in this scenario?  

We had either a laying worker or a drone-laying queen this past spring after requeening last fall (kinda strange, isn't it?) only to find a horrendous amount of regular worker cells being converted in the middle of two frames to drone cells; beautifully capped and ready to hatch.  Requeening yet again solved our problem but can we be sure we didn't have a laying worker laying all those drones?

So the question is:  can you have a laying worker in the same colony with an infertile queen?
