Did you purchase a marked queen?
Queens are different looking than workers and drones. The abdomin will be about 1/3 longer than a workers, and the dot will stand out.
Although I have not looked at MB's website, but it would be wise for you to look at it. Sooner or later, you will want to find your quuen in the colony, and it helps if you know what you are looking for. I don't mean to sound sarcastic, but until you actually see one in her natural surroundings, it can be hard to tell.
