What happened to this egg?

[Abril1127]

Can anyone tell me what happened to cause this burnt looking egg. Normally they are a light brown egg.

I have no idea, but my ducks lay weird colored eggs like that sometimes too.

Probably just a 'spray booth' glitch...tho looks like shell may be cracked?
Tell us more about the bird that laid it?
