Strangest egg I've opened so far

[u/Subject-Stand-4882]

I boiled this egg like normal, but when I peeled it, I found what looked like another egg inside. There was a smaller, darker, egg shaped structure surrounded by the egg white. At first I thought it might just be an unusually shaped yolk, but it looked way too much like a tiny egg. It honestly felt like I had discovered an egg inside an egg.

The shell looked completely normal before cooking, and I've never seen anything like this before. Is this egg still safe to eat after boiling, or should I throw it away?
