That's really your choice.
Just know if you get nattie that you lost around 7 million tu.
But if you get a color, you get a 90 mill+ gain.
So it's really up to you.
If you're aiming for color, the only way to get it is to try.
If you're just hatching to hatch, consider if you really want to spend tu on that.
Tu can always be gathered again, it's not impossible. c:
