Is this a dud? Candled (photo) anywhere from 17-20 days

This egg appeared in a clutch that my hen was sitting in and I marked it as "stolen"...and not sure when it's truly due to hatch. I think it's anywhere from 16-18 days old. It doesn't stink...the hen hatched the other two she had (Sun/Tue), this was the last one so I candled it...what do you think? Sorry had trouble uploading, pic is in next comment

dud for sure, no strong vein formation, or embryo development that I can see
