Cracked, scratched or dirt??

Hi everyone,

Trying to figure out if this duck egg is cracked, scratched or if it’s just dirt… any help would be appreciated! What should I be looking out for?

Thank you!

I think it is just dirt, cracks will usually glow when candled.

Thank you for the message.
Ok! I really hope so I’ve had some terrible luck with hatching lately
