So this is my first time ever incubating eggs or even seeing fertile eggs. I have 9 Cayuga duck eggs and one of them looks different from the rest. None have any veins yet, that I could see when candling today, we’re on day 5 of incubation. Is this egg okay? I think there is a vague smell. No movement, no veins, but when I turn the egg the content inside sort of float around. I’ve also added pictures of 2 other eggs to show the difference. The first and last image are of the egg in question and the other images are 2 separate eggs. Thanks in advance
