The chickens belong to the kingdom of animals under the bird species, and the chicken is one of the domestic birds that humans used to raise and use them and their eggs as food and trade as well.
Chicken is one of the domestic birds that humans can breed, and can be relied upon as a major source of eggs and white meat, both a source of protein necessary to provide the body with the necessary energy.
There are many forms and types of chickens in large numbers, around the world, which provides the growing needs of meat and eggs, but chickens like other living organisms have a specific life and a period of time to live, the chickens may die unless they become infected so we know the number of years that Chicken lives.
Characteristics of the shape of the chicken
And the chicken in the form is similar to other birds, but it is characterized by the palace wings and tail, which prevents him from the ability to fly, is characterized by the shape of chicken that has a “crown” at the top of the head, which is called (custom), and this custom is short in the female and large in the male, The chicken is called “cock” and differs from the female, we find that it has feathers and tail longer than the chicken but it can not fly also, and chicken is the most widespread bird in the world.
The life cycle of hen
First, the hen is vaccinated from the cock, which is the “male hen.” After laying the eggs, they lay on it for 21 days. This period is different if the chickens are raised on the farms, where the conditions of temperature and mutations are observed in these places. When hatching.
The chicken continues to feed its chicks so that it can get used to feeding itself when it is 8 weeks old. When it reaches 20 weeks, it is able to lay eggs, where its egg channel ripens, and egg production rate is about 160-200 eggs per chicken per year.
As for hybrid chickens, which receive special attention, the production rate is 300 eggs per year, but the question here, how many years continues to produce chicken. It is reported that the average useful life of the chicken is about 4-5 years.
Types of chicken
In primitive life, chickens lived with humans and grew up on the grains they ate, and the crumbs on the ground, so humans simply raised them for meat and eggs, but with the development of agricultural research and modern technology, hybridization methods evolved to produce new strains more capable of producing Commercial eggs, and other types are raised for slaughter and to obtain meat as food for eating only.
One of the most prominent types of hybrid chicken is the dokki produced by Fayoumi and Plymouth chickens. It is characterized by its white and black color, and other species are the dynasty, the silver falcon, the golden frieze, the jasmine, the mandrakes, the pundra, the hieroglyphic, the amphora, the peace, and the anchash.
