The egg white, or albumen, is 90% water and 10% dissolved protein. It's function for the developing chick is to provide nutrition in addition to the yolk.
The tried and true method is to hold the egg up in front of a bright light; a chick inside would appear as a dark spot inside the egg. Otherwise, by looking at it, you cannot tell. If you weighed it over time, the egg would become lighter if a chick were developing inside it.
i have an abandoned egg and im using a shirt and im wrapping around the egg 5 days later candle your egg an you will see your bird developing
The human embryonic membranes, including the amnion, chorion, yolk sac, and allantois, support and protect the developing embryo in the womb by providing nourishment, gas exchange, and waste elimination. In birds, the amnion, chorion, yolk sac, and allantois inside the egg serve a similar function by enclosing the developing embryo and providing necessary nutrients, oxygen, and waste removal for growth and development. Both systems play a vital role in sustaining the developing organism until it is ready to survive independently.

The primary function - is to contain the developing embryo and its nutritional yolk-sac until the foetus is ready to emerge. That applies whether it's a hard-shelled egg like a bird, or a soft-shell like a reptile.
When a bird's egg is fertilized, a chick is developing inside.
yolk
It's a sack and not an egg but the primary food source, the only one, is the placenta and the nutrients go via the umbilical cord.
The embryo in an egg is the developing organism that eventually hatches into a new individual. It is responsible for growing and developing the necessary structures and organs needed for survival outside the egg.
The egg yolk is the part of the egg which feeds the developing embryo. The egg white protects the egg yolk and and provides additional nutrition for the growth of the embryo.
Both provide nourishment to the developing young
No, an egg is not considered a tissue. It is a reproductive structure produced by female animals, and its function is to protect and nourish the developing embryo.
Producing eggs is the primary function of the female reproductive system.
Zygotes are formed by the fusion of a sperm and an egg and are the first stage of development in a new organism. Their primary function is to undergo cell division and differentiation to develop into an embryo.
