What is wrong with this egg?

[Cut-&-Shoot]

I've never seen an egg like this. It looks like something has been crawling around inside it. Should I try incubating it or not?

Not sure...do your hens lay their eggs in hay?

What type of bedding is in your nest box?

I got the eggs off ebay. Out of 14 eggs this was the only one like this.

kinda looks like the imprint of a nest box pad or something in the bloom

Ask the seller what it is...they should know.

YES!
Probably something exactly like this.
