If they go bad won't they get a funky color of grey on the outside of the shell too?It happens yes. But if you keep an eye on those ones you thought were bad you should be able to grab them as soon as they are for certain dead. My eggs looked similar to what you pictured but had veins I couldn’t see the veins in you picture which was why I asked. About 4-5 days later they looked pretty normal for eggs. Hopefully yours will do the same.
