Hatching Bob Whites

[Chicken RN]

I ordered some fertile Bob white quail eggs online. We are on day 8 of incubation so I candled to see if any needed to be discarded. I have a few that have this curve in the fertile area some eggs the curve is smaller but it is still present. The development in egg is pretty much equal to that of the others. Is this a sign of an egg that won’t hatch or that would produce issues later?
thanks for the help!!!

I don't think that's a problem, but the quail experts hang out here: Quail Hatch-a-Long If you'd like to share your pictures with them, I know they'll help you out.
