How to raise chickens - The first ten weeks is a growth and formation of bone tissue, bones and muscles. The younger chick is formed musculoskeletal system. This is an important period in terms of maintaining uniformity, as if flocks of birds' skeleton are about the same size, and then continue all the physiological indicators of the size of attached to him. At the 10th week (end) in all groups - like small birds, and at large - it is desirable to obtain the average weight of birds (chicken), just over 1 kg. Further, on the 15th week, the target weight will be 1.5 -1.6 kg, and further weight gain of chickens must grow every week, from 90g. at 16y to 175g. On 20th-22y, when the chickens are ready to lay eggs. This is achieved by the amount of feed per bird begins to increase with the 15th week.

Raise chickens - Adjusting for weight gain, maintain uniformity in the herd is achieved by controlling:

1. a uniform forage income per head rising stock (this is achieved by the organization received food in the trough, depending on their type of regulation time, during which feeding is carried out, the ratio of nutrient / volume of feed, etc.)
2. Population groups hens that are kept together (not too overpopulated area).

15 week - is a definite change in the physiological maturation of chicken. During this, period, held their last sorting by weight, but it is desirable to achieve uniformity in advance, because from that moment the weight of chicken begins to affect the rate of maturation of the ovaries. If the weight of the birds will be less than 1,5 kg., Then the eggs will generally be small, there will be many, but they will have many defects in the shell and low fertilization, and these chickens are prone to hatching eggs. Incidentally, the latter is extremely undesirable for poultry farms, can be specially cultivated in a household with a certain group of chickens (if you do not plan to carry out the incubation of eggs). If the hens at 15 weeks, weigh more than 1.6 kg., the eggs they will carry a little before the others, their fertility was also low, the eggs will be a little bit, but they are large. Therefore, in the household, such hens can be a valuable source of high quality edible eggs.

Between the 15th week of 20-22 - this is the last time when we can bring about chickens to the general, identical weight. Problem further period - is to become through puberty with the maximum number of quality layers, producing a good hatching eggs. Table egg will always be enough, they should be regarded as a kind of waste from the production of hatching eggs (as on incubation is not necessary to transfer the eggs with rough shells or irregular shape, too round or too sharp, with two egg yolks, etc.). Namely, hatching eggs is a reserve for the future reproduction of the herd chickens.
