Yolk Sac still attached, is it genetic?

Protein needs to be higher but also the extra vitamins and minerals do a lot of good too.

So after talking with @BlueShadow some more I think it very well could be a feed issue in our breeding stock. I wonder if this will effect all the other eggs. As much as I don't want to do it, would I just be better off culling these and not putting them through the misery? Is it even possible to save them once they hatch? Is there very good success rate of saving them and them growing up to live a normal healthy life to use as breeding stock?

Certainly some people on here have saved chicks with unabsorbed yolk sacs with lots of care and they grew to be healthy birds. These chicks look better than your last batch because these yolk sacs are smaller and don't look infected. If you want to give it a try, they have a better chance than those did.

I see people save these chicks all the time.
Separating them and applying neosporin does wonders.
