they are less like cracks and more like fractures I guess, there is no noticeable shell distortion or crack, you only see it under great lighting or when candling. so I figured i'd leave them be. so far they are developing well. I've marked them to identify later after hatch to see if there are any disparities.You learn something every hatch.
Your chances are better, not being shipped. You can put a little nail polish on the cracks to seal them.
