placenta
The yolk supplies all the nutrients for the growing embryo.
Technically it isn't called a baby but it can lay eggs which a chick is inside of.

When baby animals grow in eggs they are growing their organs that are needed. The eggs help protect the baby while it grows big enough to live outside the egg.
Eggs do not require feeding. Eggs contain all of the nutrients that the baby needs inside them.

Baby fish are typically produced when a male fish releases sperm into the water and a female fish releases eggs. The sperm fertilizes the eggs, which then develop into baby fish. This is known as external fertilization, and the fertilized eggs are often left to develop independently in the water.
Platy fish are livebearers, which means they give birth to live young rather than laying eggs. The female platy fish will carry the fertilized eggs inside her body until they hatch into baby fish, known as fry.
When birds lay eggs they usually sit on them and keep them warm. Just like when a human is pregnant, our baby stays warm inside our body. If we freeze to death outside, our baby would die. If the eggs aren't kept at the temperature of the parents they wont be warm enough and they baby birds will not grow inside.
Jaguars are mammals and the mother gives birth to live young.
