It takes around 21 days for the egg to hatch the chicken.

It's hatch, and about 30 days.
15 days to 1 month
A fertile chicken egg contains an embryo, which is what grows to become a baby chicken, gradually consuming the egg yolk and the egg white in the process.
21 - 23 days
about 21 days
as long as it takes for you to get a hammer and open that thing up
It depends. Did stay out in the cold for too long? If it did it will hatch but maybe become sick or die in the egg
21 days, give or take a few days.
They most likely will not hatch at all.
The egg, 1st of all because there were eggs long before birds, but if you mean a chicken's egg then it is still the egg. This is because when a new species evolves, the egg is say, given birth to a sub-chicken, and the new species (chicken) is inside the egg, which is techically now a chicken's egg.
Ushally it will take a chicken about 1 or 2 days before another egg is layed but if you let kids and dogs and other animals chase the chickens it will be stressed out and it will take longer for the chicken to lay an egg which is about up to 3 or 4 day to lay another.
The actual formation of the egg inside the chicken takes about 24 hours, but when they sit down to lay the egg it can take anywhere from 15 minutes to a couple of hours.
