chickens usually grown on the floor, using the litter.Sometimes contain poultry poultry in cages or mesh floors.
Floor content
This system provides space chickens on deep litter of loose and moisture capacity of materials with low thermal conductivity.When the outdoor cultivation of a bird can no longer move, and this has a positive effect on her health.Before boarding party birds litter laid a thick layer of about 20 cm. It is removed only after the poultry.
Content on mesh floors
If one square meter in the outdoor cultivation accommodate up to five birds, when grown in mesh floors - up to twelve animals.It increases the capacity of the house two and a half times.
hens in cages
This method is more advanced as compared with the placement of the bird on the mesh floor.So found the bird on large poultry farms producing eggs.The apartment house hens in cages almost no one does not.
But how is the feeding of laying hens?They eat two times a day with full-dry foods.The level depends on the amount of filling feeders pour feed.It should not exceed two-thirds of the trough.
feeding dry forage daily rate includes: one hen for about 120 grams of food.During the year a chicken consumes about 44 kg of feed.If the diet of laying hens included succulent and green fodder, the amount of the daily requirement increases to 170 grams or more.
Lush and green food has beneficial effects on the body laying hens, their productivity and viability.We tried to find out why the hens and roosters are colored differently.We can see that neither the content nor the color of the breast feathers have absolutely no effect.
Chickens probably - the most common bird on the planet Earth.According to some estimates now their number exceeds 13 billion!Humanity receives from females about 600 billion eggs a year.
Of course, everybody wants to know why the hens and roosters are colored differently.But you must admit, this question does not interest anyone, when the table for dinner served delicious fried eggs.
