Ok, So I've always wondered. The chick absorbes the yolk. But Does it absorb it before or after it absorbs the veins on the membrane? Which comes first??

Does it start absorbin the yolk then the veins, then finish off together. other yolk first the veins.

I've wondered becuase I've had some hatch with no veins there and then they have some yolk after and some hatch with veins, and all the yolk absorbed and both!
