I believe I may have a problem brewing with one of my eggs. I cut this egg after worrying about the size of the egg and a few water stains beginning to show up on the shell. This little one has been in its egg for a little over a day now and while adding some water to its egg I noticed that the cord seems to be wrapped either around itself or its yolk sac.

Can I get some experienced feedback? I don't cut eggs normally and I don't know what's normal and what isn't when it comes to the yolk sac inside the egg. Should I be seeing the cord here?
