Most poultry farmers only have chickens for the first two years, which is due to their optimal productivity during this period. But how many chickens live at all? Virtually none of the farmers will not answer this question. To find out all about the life span of poultry, read on.
Life cycle features
Many factors affect the life cycle of a chicken. First is the cultivation of poultry on a domestic or industrial scale. Secondly - the breed of chickens themselves are very influential. Thirdly - this, of course, the diet and content.
How do growing conditions affect?
So, the first significant factor is where the bird will be grown. The fact is that on farms the age of a chicken often does not exceed 3 years. Such a short life is due to the productivity of the bird itself. For example, laying hens are highly productive only for the first two years of life, and then egg production declines.
And if we talk about meat rocks, then their age is influenced by the taste of meat. The older the bird, the more its meat loses its dietary properties. Therefore, to keep such chickens for more than one year does not make any sense at all. But among poultry breeders who breed their wards at home, chickens can live up to 6-8 years.
How does the breed affect the age?
As you know, chickens are divided into egg, meat, meat and decorative and breeds. How many years a poultry will live often directly depends on which of the breeds it belongs to. So, for example, laying hens live no more than 3 years. Selection of birds is carried out from the first year of life. First, the least productive hens go to the expense, then the second year the selection procedure is repeated. Three years of age can only boast the most productive individuals.
As for meat breeds, there is still more severe. It's all about the taste of meat. That is, the younger the chicken, the better the meat will be. Therefore, farmers give them special food additives that accelerate the growth of poultry. The answer to the question: "How many years have these chickens lived?" - will be no more than 45 days.
And how much can meat breeds live? Here you can also talk about why they are divorcing. But, based on the fact that they are often bred at home, sometimes their age can reach 5-6 years. As for decorative breeds, the age of some individuals can reach 10 years.
How does the diet and content?
Also, how many years a chicken lives is directly affected by its diet and housing conditions. If the conditions are bad or the diet is wrong, then it is unlikely that she will live, at least up to 1 year. But if everything is in order, the average age reaches 4-5 years. This figure is due to correct or enhanced diet and proper content. Under such conditions, the bird will give optimal returns, and its biological resources will be exhausted after about 5 years.
A very long life of decorative rocks due to the right content and diet. It was the latter that made it possible for them to extend their lives to at least 6 years. Also recently, Japanese scientists have reported that a hunger strike has a positive effect on birds. For the experiment were selected old individuals, which have long ceased to carry eggs. Selected bird starved for 1 week.
Then the feeding was resumed. The effect of such a procedure was overwhelming. The chickens began to renew their plumage, their scalps reddened, their voice changed, and they also became as energetic and mobile as the young. But the most interesting event was the resumption of egg production.
How many years have chickens lived - results
As you can see the exact answer to how many chickens live, no. The duration of their life is influenced by many factors that can be related and unrelated. One can definitely say that a hen on the farm will live no more than 3–4 years, and meat breeds will not be more than 1 year old. But if we are talking about domestic breeding, then they can live to be 6-8 years old.
Also need to remember the oldest chicken in the world. Previously, it was a 14-year-old laying hen who died of great age. But the chicken-Gunnusya from Poltava region in Ukraine significantly surpassed it. Now she is the record holder of the Guinness Book of Records. It is known that it belongs to decorative breeds, and its age becomes 18 years.
