My eggs seem to have lost an air sack

What type of incubator are you using?
Where did the eggs come from...your own stock?
If so how long have your girls been laying?

I am still learning candling technique so I am popping to listen to the expert panel.

It's hard to tell if it's just the pics, but I would expect to see more veins than I do earlier on in the process, and much less light coming through for day 15. I agree he looks iffy :/

My day 15 eggs were not letting ANY light through except for the air sac. I candled 103 eggs on day 15 or 16 and what I see here looks a lot like my duds, many of which I cracked open then to check. If you do decide to pull any of these, crack them to see how developed they are if at all. It will give you a better idea as to what is really going on in an egg when you are candling. I have to agree with @Texas Kiki, not to mention she is far more experienced than I am.
