Food and equipment are located next to the nest. These warehouses may be built in the middle of the nest or alongside the nests. In this type of building, labor and worker cost savings, and on average cheaper than the previous one, but it is more difficult for health and disease control than the disease is spreading rapidly among herds. Hence, for the control of the disease, nests are often divided into several small livestock with wired and even brick walls. In all large farms and poultry farms, these nests are used. C) Multi-storey nests - these buildings are made of 2 floors or more. Typically, these nests are more often considered in commercial and large poultry establishments, especially around cities, which are difficult to land and expensive, because these buildings firstly require less land, and thirdly, for ceilings and floors to the extent It will be saved. If used for eating and drinking automated means of automation, it will save a lot of money, and in the United States and Russia, this kind of nest of buildings has recently become commonplace, often used in such buildings to keep chickens in a cage way. Such nests are, firstly, expensive, because the construction of such nests requires a more detailed material and construction plan, the cost of which is beyond ordinary courtiers. On the other hand, these buildings are heated in hot spots such as Iran in the summer and their cooling is difficult, and for this purpose mechanical devices are needed. Hence, these buildings should be built in places that, like Russia, have very cold winters and mild summers. Third, it requires more work to carry food to the upper floors, as well as egg collection, etc. Unless special lifts and automatic feeding devices are used, eggs are collected with automatic devices. Classification of poultry buildings for breeding: For the time being, poultry keep nests for keeping chickens and hens and eggs, but nowadays they are not advisable in terms of health and economics. Today, in poultry farms, depending on the age and purpose of breeding, a series of buildings and structures are used, and in no way does one-day-old chicks stand up in the part where egg-eggs are grown. Similarly, young chicks do not grow in a nest besides day-old chicks. For breeding purposes nests to be considered for poultry should be for different ages: ▪ Nest for chickens at Brody House or Mother's Room. In these nests, one-day-old chick holds up to 8-9 weeks. As mentioned in the discussion, chicks of this age can not heat themselves due to the incomplete control of the central heating control device and hence need artificial heat. In the building of such nests, care should be taken to ensure that the chickens are supplied with heat and that the ventilation is well done. These nests may be constructed individually or multi-tiered or even multi-storey, but typically slaughtered individually for this purpose is more likely than other species, but if the keeping of chicks is carried out in large quantities. Row buildings can be used. The nests are constructed in a row or in two rows in a series, even in some fields, crosswise. Chickens may be separated from each other by walls of wire mesh, each in which 5000 to 10,000 chicks are kept. The floor of these nests may be made of construction materials or wired wire. The chickens are not used in the nest of the chickens and keep the chickens confined and confined because it is easier to control the health system and there is no risk of a cold. On the other hand, the risk of rabies of wild birds There is no particular crow in the building of these nests, so that sunlight is well nailed to the nest and its ventilation in cold seasons and cooling it in warm seasons is easy. Chicken Nest Broiler House - In some farms, usually after 6 weeks, chickens are transported to these nests. At this age, the chicks do not need extra heat, and the nose temperature (22-22 ° C) for They are enough to keep the benches usually 4-6 weeks in the nest, and after that, if they want to grow grilled chickens, they send them to the market or slaughterhouse, and if they are to make eggs, they will close them to the hut Others pass. This stage often takes between 1-3 months depending on the season and breed and breeding style. After the end of the maintenance, it should normally disinfect the nest completely and dispose of the new series. Today, in order to save money, they usually hold the benches from the first to laying in a nest. The nail floor may also be made of bedding or wired tours. In some countries, large cages are used to nurture chicks, which is placed in a 40-50 cage per lane. This category of nests may also be separate, rows and even multi-storey. ▪ Nests for keeping young chickens - usually from 12 weeks to a few days before the chicken starts laying the young pups (Pullet) in special nests called waiting nests. The conditions of these nests should be limited in terms of equipment In the middle of the nest of the trusses and nests of eggs. During the time the young chickens live in these nests, they are being prepared for laying eggs
