They don’t need flow nor tumbling FYI, they aren’t like fish that carry eggs in their mouths.
I had best results dropping eggs among gravel substrate to shelter them from being eaten by other shrimp and had greater survivability than other methods (in part likely as they hatch without fully developed swimming parts and hungry, so being right with biofilm on the substrate is ideal).
So anyway, yes, it’s totally likely they’ll hatch! 🙂
Look up “shrimp egg tumbler”, you can easily make one to suspend them above the bubbler. They need to be in flow, since the mother is no longer fanning them.

If you have no scavengers in the tank which will eat the eggs, they have an OK chance of hatching. You’ve done what you can do. Good luck!
