A hen begins to lay eggs when it reaches maturity. As women produce an egg each month regardless of sexual activity, chickens produce an egg every day no matter if they have access to a rooster or not.
When it reaches maturity, the hen begins to lay eggs. Not all mature chickens at the same age; this varies by race and environmental factors. Usually hens begin laying eggs field five or six months old. The first few eggs laid can be very small, irregular or with a little blood on the surface; it may take several days to put another egg. All this is normal and is due to the natural process of growth and adjustment by passing the body in the “adolescence”.
Once this stage of physical maturation is regularized, the hen will lay one egg per day … if all conditions are pleasant.
More information: What need hens to produce an egg a day?
To lay an egg, the chicken first have to find or build a comfortable and safe nest. For hidden but with enough space to turn full circle and an escape in case of attack by a predator place. Once you find a suitable space, will use the same nest until the end of its cycle (unless something happens to disturb him, then look for another nest).
At the beginning of its cycle, the hen lays her egg in the very early morning. Every day gets a little later.

In a natural situation, the eggs remain in the nest until the end of the cycle, so the first day in the nest would be empty when the hen is cast, the second day would have an egg, the third day two, etc. The last day of your cycle, the chicken becomes culeca. You may lay an egg that day or simply go to their nest and thrown to incubate the eggs that are already there, without putting other. Peasant and native hens have a cycle of 8-15 days while some commercial breeds never become culecas.
(Following the natural situation): From the last day of your cycle, the brooder seems to go into a trance. It will remain in this state 21 days until the chicks are born. During this time she turns her eggs periodically and regularly gets up to eat and drink. On a hot day, you may leave the nest a good time while looking for food and stretches, if the day is cold or rainy maybe he will not rise throughout the day. It is important that the hen culeca have access to food and water so as not to weaken while the eggs incubate. The birth of the chicks may take one or two days, she will be cast until all born (although some chickens get tired and get up when they have already been born two or three).
The hens follow this natural pattern of behavior (according to the characteristics of the breed) regardless of whether gallo or not. Obviously, without rooster fertilized eggs and chicks they can not be born, but the hen does not know if her eggs are fertilized or not. She follows her instinct to incubate. In fact, some hens will lie if their nest is empty, or be incubating eggs unfertilized much more than the 21 days it takes a chick to be born (although an unfertilized egg rots and breaks before the 21 days, leaving a horrible) odor. Farmers take advantage of this trend chickens hatching turkey eggs, which takes up to 28 days to hatch.
If there’s cock and / or eggs are collected every day, the hen laying eggs just follow according to their cycle. If a hen is hatching an empty nest the’ll have to raise. This task can be much more difficult than one would think.
