Thank you for supporting the creative commons movement !! Roosters and chickens are raised primarily for their meat and their eggs. They also use their feathers, and some varieties are bred and trained for use in cockfighting. Recent studies show that genes latent in domestic production rooster teeth in the jaws. Also for the same reason it was discovered that some chickens before birth will have a longer tail, shorter then shortly after birth. The chickens feel safe under the dominance of a rooster, and only defend by force if they are away from the dominant rooster. If he dies the dominant rooster, the next in seniority takes charge immediately. The breeding season begins in spring and lasts until the summer, with the intention that the chickens are born under the summer heat. Between 2 and 4 weeks after birth and chickens have feathers, and 8 weeks and have adult plumage. At 8 or 10 weeks are expelled from the group by their mothers to form your own or join another. It is believed that the chickens came to Europe through the great migrations of Indo-European peoples about four thousand years ago. In the low Middle Ages took the chickens as fine meat. The people also ate the meat. In the late Middle Ages and the European Renaissance hens are of great importance in the diet. Chickens are great pets because they are noble and not aggressive, trained roosters for fights are usually aggressive among themselves and rarely in humans. In some cities in the United States are allowed to have chickens as pets but this practice is not adopted across the country. Chickens are generally very easy to care for because their food is cheap. In industrial agriculture are hybrid chickens are used, which are not suitable for further breeding. Fattening and laying hybrids are bred and marketed by the world's only four corporations. Historically, the Mauser was the chickens through the winter and the associated shorter daylight periods and other environmental stress induced. This led to rising market prices, since eggs are scarce at this time. Therefore, chicken farmers had an interest to delay the moult their chickens as long as possible in order to benefit from the high prices. In modern production contexts influence of stress that would cause chickens to molt, resulting in about a laying season to a drop in egg quantity and degrades the usability of eggs missing. Domestic chickens can fly a few meters wide, but they are ground oriented ratites. Chickens are very vigilant while foraging and chat to on in cover-rich landscape. To find something edible, they often scrape their feet on the ground. In her stomach crush Gastrolithen the hard food. Laying hens usually die earlier than wild chickens, which are not exposed to the stress of constant egg laying. From the age of two years, the egg production decreases markedly. Since the Romans, the chickens bred in a big way as eggs and meat suppliers. Columella Advisor on Agriculture contains numerous references to the keeping of chickens and mentions several breeds. To the biodiversity to obtain, raising thoroughbred chickens is desirable, this breeding work is done, however, almost exclusively by hobby breeders. Economically breed chickens play as good as no role in the agricultural industry is dominated by a few down depending on the use to rapid growth or high egg production "optimized" hybrid lines, whose genetic material is in the possession of a few internationally active companies. Breed chickens are bred according to the provisions of breed standards. The chicken is the most common species in the world. With 52 billion chickens, there are more than 7 chickens for every human being. The first domesticated chickens were around the year 700 BC. in Southern Europe rightly. Today, chickens come from virtually anywhere in the world. Chickens tend to pick up, which is remarkable because their objects to red comb and wattles themselves are red. When a chicken pecking once bleeds through, it may therefore happen that end up dead chickens pecking each other if they can not go. The skin on the legs of the chicken is made ​​up of scales, such as reptiles. However, reptiles have scales on their body. Chickens have three toes and a rear toe, except the side grouse and houdan, which have an extra toe. Chickens also have sharp nails to participate dig and scrape well.
