From my experience with eggs, which is limited, eggs that develop and look like the one on the left always turn into deformed or dead tadpoles. Often their heads are mishapen or they just don't make it and die inside the egg. I've had strange looking eggs go bad and then the fungus that develops on those spread to other good eggs so you might want to consider removing the bad egg. Good luck,
