Fake or real eggs?

[Merlin]

Dear all, 

 

I am new in this forum!

I want to check if the eggs on picture are real or not?

 

Thanks for response already!!

Your pictures are not nearly detailed enough.  All I can see are 2 grey half-spheres on a red background.  I cant see any shell texture, patterns or expected break lines.  I lean more towards concretions without better evidence.

looks like eggs with lost or bad shell, but with better pics would be easier to decide
