Where does food of the developing chick?

Here's a breakdown:

* Yolk Sac: This is a large, sac-like structure within the egg that contains a rich, nutrient-dense substance called yolk. The yolk provides the chick with all the energy and nutrients it needs to grow and develop before hatching.

* Development: As the chick grows, the yolk sac gradually shrinks as it is consumed. By the time the chick hatches, the yolk sac is usually completely absorbed.
