I have no idea what you are trying to ask as even though your question is grammatically correct it is not understandable.
The hen LAYS on the egg
17 days for an egg to hatch out
After twenty-one days after the hen has laid the egg that the roster has fertilized the egg will hatch.
yes you can hatch a egg without a female hen providing that it has been fertilized by a cockerel this is what you call incubation which relies on heat to hatch the egg this acts as the same way as any hen would to the eggs when she sits on the nest.
A fertilized egg is an egg that is fertilized - in short terms, it can be incubated and a chick will hatch from it after incubation.
21 days from the day the hen begins to brood.
I watched the egg hatch.We decided to hatch the plan in motion.Close the hatch, you're letting the zombies in.
Yes- if the egg is fertilized, a chick will hatch out from that egg.
Yes.
Yes, only the hen sits on eggs.
You can take them as soon as they are laid. Usually the hen moves off the nest and leaves the egg. However, if she is broody, then she may sit on it hoping to hatch it. If that is the case, just gently reach beneath the hen and remove the egg. She may peck at you, but that's OK. Once the egg is gone, she'll then give up and move away.
Depends if the egg has been fertilized by the cock, and the temperature of the enviroment.
