At one year of age their body size and feathers are of the adult type, however they are capable of laying eggs and breeding at a much younger age, for production egglayers it is around 5 months of age.
You allow a white leghorn hen to mate with a white leghorn rooster. The eggs produced by that hen are then incubated for 21 days and a chick emerges from the fertilized egg. That chick will grow to be a white leghorn chicken.
A fertilized egg takes 21 days from the day incubation starts to hatch. A broody hen may take a few days to gather enough eggs but the day she starts to set on the eggs it usually take a full 21 days. Constant temperature and humidity must be maintained by either the hen or the artificial incubator.
An egg must incubate for three weeks, 21 days, in order to become a chicken. During that time the embryo inside develops into a chicken in much the same way that a baby grows inside its mother's womb. The difference with a chicken is that everything the chick needs is included inside the egg. It absorbs the nutrients as it grows, and by the time the chick is fully developed and ready to live outside the eggs the chick has completely filled the space. It hatches able to eat, drink, walk and run. Chicks typically stay with their mothers until they have all grown all of their adult feathers.
Most breeds are fully feathered at 50 to 60 days old. See related links below for a good site to view the stages of a growing chicken from hatch to one year. Look for the growing chick link .
To help a chicken egg hatch, ensure proper temperature and humidity in the incubator. Keep the egg still during the hatching process, and resist the urge to assist the chick in hatching as it can cause harm. Provide a warm and quiet environment for the chick to hatch naturally.

If the chicken laying the egg has been fertilised by a rooster then it is possible to get a chick out of the egg if the chicken goes "broody", alas it sits on the egg(s) for days.
A baby chicken has a rather short history. When it comes out of the momma chicken as an egg it takes only 21 days for that egg to be formed into the chick. From the day that chick exits the shell, it walks and eats and learns to live on its own. Follow the link provided and see how the chick develops.
15-30 days for ducks...
It takes around seven days for a chick to grow into a full grown Chicken.
It protects the newly forming chick for the first 21 days. The shell holds the yolk and albumen together creating a barrier from dirt, germs and trauma. It is natures "safe"container designed to allow the embryo to mature enough that the chick can develop.
If you want to ask how long a chick (baby chicken) is in an egg for, it is usually around 21 days depending on the breed etc.
Chicken are not really born. Unlike mammals, chickens are hatched from the egg laid by the hen or female chicken. The hen lays a fertilized egg in a nest and if that egg is incubated for 21 days a chick will emerge from the shell.
A fertilized egg takes 21 days from the day incubation starts to hatch. A broody hen may take a few days to gather enough eggs but the day she starts to set on the eggs it usually take a full 21 days. Constant temperature and humidity must be maintained by either the hen or the artificial incubator.
To hatch a chicken egg at home, you will need an incubator to regulate temperature and humidity. Place the egg in the incubator and turn it several times a day. After about 21 days, the chick should hatch. Make sure to provide proper care and warmth for the chick after hatching.
