Anyone know what this is? Developing Duck Egg

[houlahoula]

I have never seen this type of spot in an incubated egg before. Doesn’t look good to me! The embryo is still moving and alive for now. I don’t know what to expect though. Anyone able to offer their advice or make suggestions? Thanks in advance!

IDK but I've had this on some of mine and they hatch perfectly fine...

Well that sounds hopeful! Just have to let time pass and monitor for changes before lockdown. Every hatch is a learning experience.
