The embryo (fetus is a term usually reserved for placental animals) will start to grow on the germinal disc on the yolk when the egg is incubated. Celluar division can start as soon as the egg temperature goes above 85 degrees F, but isn't optimal until it is 99-100 degrees F.
Uterus. The fertilized egg continues to grow developing into a fetus.
No. All fetuses start off as a cell which is called an egg. But human babies are not inside an egg like baby chickens are when chicks are born. Human babies do not need a shell, because the mommy's belly gives the fetus protection for the entire time. Chicks must grow inside the egg shell but outside of their mommy's belly.

It provides nutrients for the fetus to grow.
Once the chickens start to sit, the chick starts to grow. You can start to see the the embryo develop after 4 to 7 days if you candle the egg.
A female's fertilized egg spends the majority of time in the uterus. This is where the egg will mature and grow.
The color of a chickens egg IS by the color of the layings chickens ears.
A bird's egg is a self-contained unit. Everything the fetus needs to grow to birth weight is contained in the egg. The yolk provides the nutrients to bring that single-cell egg to birth stage. In humans, the nutrients are provided from the mother to the fetus by the umbilical cord.
Yes, but you should make sure that the fetus has not begun to grow in the egg.
The fertilized egg (which develops into a baby eventually) implants itself into the uterine wall/lining. The lining surrounds the egg as it matures and develops into a fetus and a placenta and amniotic sac surrounds the fetus eventually to nourish it.
Chicks grow rapidly from the time they leave the egg shell. They are relatively small for the first two months and then start to look like adult chickens. Here is a link to see the growth from 1 day to 16 weeks.
