Externally fertilized
The internal structure of a chicken egg consists of the yolk, which is the yellow part containing nutrients for the developing embryo, the albumen or egg white, which provides protection and additional nutrients, and the shell membrane and shell that protect the contents. The germinal disc on the yolk is where fertilization occurs, leading to embryo development if the egg is incubated.
Birds develop internally, within the egg, where they undergo rapid physical changes before hatching. The egg provides protection and nutrients for the developing embryo, allowing it to grow and develop until it is ready to hatch. Once hatched, the bird continues to grow and mature externally in its environment.
Donno lor
a chicken egg is about 50g :)
Simply because they reproduce by means of internal fertilization. The embryos either develop externally inside a soft-shelled egg, or internally in the female reptile.
yes because the chicken is inside of the egg.if the chicken wasnt it would be called just an egg
the egg because dinos lay eggs
seagull's eggs are about the size of an average chicken egg to 2x the size.
From an evolutionist's point of view, the egg came first. A chicken, by definition, must be born from an egg. The egg does not have to be a chicken's egg however. The egg could be layed by an avian that is very similar to a chicken, but which is not a chicken. A small mutation in the genes produces the chicken offspring, which in turn lays eggs to produce more young.
The Chicken!!!! If it was the Egg who sat on the Egg for it to hatch?? Nobody so... God made the Chicken FIRST!
a chicken? its like the question: what came 1st, an egg or a chicken.
egg
