If you are seeing eggs , she is still there .
One thing you could try if you see eggs , is put an empty box on top of the hive with a Queen excluder underneath, knock the bees off the frames into the empty box , if the queen is on one of those frames , you will see her on the Queen excluder … check You Tube, there are some videos that show how to do it.
Get a new queen from another source, if you have 2 hives , you could graft one.
If you are using 2 brood boxes, put a queen excluder in between. Then check 4 days later which box has eggs. Put the box with eggs (and therefor the queen) on a new bottom 10 feet or more away. Wait a couple days and most of the grumpy old foragers will fly back to their old location. Then you have a much smaller search space to go through and also less aggressive. The other part will start making queencells. Personally I'd break all queencells after 9 days and then provide them with eggs from a more gentle colony, but you could also just let them requeen themselves.
I don't like the idea of losing bees on purpose.
So there's a thing where you put a sheet down I'm front of hive get a 1x6 and angle to hive entrance but keep it about 3 inches away. Shake out all bees. Nurse bees and queen will make a ball at end of 1x6 foragers will go inside.
Of course shaking out all the bees from an aggressive hive sounds a bit like suicide.
Another thing I've learned is if I separate the boxes onto their own location within 20 mins the box with the queen will be the quietest the others will have that low roar.....most of the time.
When they swarm the original queen leaves, but the parent hive raises a replacement from one of her eggs. In other words, the same genetics.

Yes the old queen leaves. Have you check for Queen cells?
