    I assume you got your answer, but I'll give it a go anyways.

    The yolk nurishes the chick throughout incubation, but the embryos really start absorbing it when they begin the hatching prcess around day 19. Once the yolk is nearly completely absorbed, they will hatch. They absorb the yolk by struggling, the more they struggle to get out, the more yolk is absorbed. If you could give me an idea of how big the yolk sac was, I might be able to tell you at what stage it died duing.
