Yup. Twins. Probably even a 2 membrane double yolk.

Crack that bad boy open, because it's 99.9268% non-hatch-able.

I just completed a hatch of coturnix eggs with one huge egg, double yoke they were fully formed just didn't pip out.

I had a double yolk muscovy that one developed almost all the way but never hatched. The other yolk was just a big mush.
