If you are finding brood and eggs and the hive is growing in size. Things are good, I don’t spend much time trying to find the queen unless I absolutely need to for re-queen. I find it to disrupting for the most part. If you find brood and eggs things are good you can also determine if Mother is home by the demeanor of the bees. They will be calmer and the buzzing will seem even. When they are queenless they will roar when you open the hive and they will be more aggressive.
Laying workers is actually rare, and will normally happen if they become hopelessly queenless. But conditions need to be right for this to happen, no brood capable of becoming a queen. If you have eggs and brood in various stages of development they will produce another queen. And the colony will recover from the loss of the queen.
But what you are writing things sound very good. Relax and enjoy, you will soon learn what’s normal and when something is amiss .
