>I have been queenless for the past 10 days.
How do you know?
> Don't know how or why, but I have made two checks and I just can't find her masjesty.
Not being able to find the queen, does not prove they are queenless. Not being able to find any brood or eggs, does not prove them are queenless. Not being able to find any brood or eggs for a couple of weeks only makes it LIKELY they are queenless.
There are too many reasons to list why you might not find the queen, but one is that a virgin queen is flightly and hides.
The reasons you may not find brood is that the old queen died, was replaced, or swarmed and you now have a virgin queen. By the time a replacement queen is raised and laying there will be no more brood in the hive at all.http://www.bushfarms.com/beesmath.htm
The only way to tell for sure if there is no queen is to give them a frame of open brood and eggs and wait a couple of days. If they start queen cells, then they are queenless.
