The eggs have to be fertilized before being laid in order to "grow" a chick.
No most hens eggs for the human food chain are infertile
all eggs are screened for fertility (blood spot in egg if fertile)
any fertile eggs are removed before packaging.
Most battery eggs are infertile,
there is more chance of a fertile egg from free range chickens.
It can do i had two hens sitting with six eggs each they both hatched three chicks all eggs had chicks in them but three from each had died in the eggs
no they lay eggs THEY DON'T!! but some chickens lay eggs that turn into chicks over time
The embryo consumes the yolk, and cells turn it into more of the chick enabling it to grow.
Yes. Chicks come from fertilized and incubated eggs.

I don't think there is scientific explanation for that. What I know is that that is a question for God not humans since it is He who makes all happen.
A peregrine falcon is a bird of prey, and the chicks do hatch from eggs.
The chicks should all stay in the incubator until the hatch is complete and the chicks are fluffy and dry. They should all be moved to the brooder box at the same time. The chicks will roll the peeping eggs and that is ok. Sometimes the movement of the completed chicks will get the emerging chicks to begin and that is a good thing. Do not be hasty in removing the newly hatched chicks from the incubator, they can and should remain in there for up to 24 hrs.
They turn their eggs so they can be heated evenly on all sides.
All eggs have yolk. Fertilized eggs will have a little white circle on the yolk. Unfertilized eggs will have an oval instead of a circle on the yolk.
Yes, turning the egg is natures way of centering the yolk in the albumen as it develops. The egg can be turned more often without ill effects but at least twice per day for 18 days is recommended.
No.
