what is going to happen next!

[plecostrum]

I collected lots of mated queen hoping to find a Lasius flavus. but due to my overactive son we ran out of space so the last resort was petri dishes after looking this week one has 7 queens in with lots of eggs

So my question is what will happen next?
will the worker hatch and except all the queens?
will the queens fight to be queen?
I just do not know?
Should I choose one queen and remove the rest?

If the queens are nigers, they will support each other until the first workers arrive. There will be one dominant queen, the rest will be killed. The remaining queen will bring up the other queens brood.
