The soil of open areas where broilers have been raised for a long time can be contaminated, ie. be so contaminated with pathogens that it becomes dangerous to the health of birds. The soil should be regularly inspected for parasites and their eggs and larvae. The time for which the soil is heavily polluted is different and depends on its type and the density of cultivation. In this regard, it is important to take various measures to prevent pollution, such as moving the houses (in cases where they are mobile) to a new pasture area or to apply the principle of rotation of the pastures when the premises are stationary.

Sufficient space must be provided for all birds in the houses or in solid rooms so that they can be sheltered at any time. In bad weather, birds may be confined inside and not allowed to graze when it is judged that their welfare will be endangered.

Birds should be encouraged and encouraged to go outside by providing fresh vegetation, clean water and shelter and shelter in pastures placed far enough away from buildings so that birds can graze, dig and move.

When determining the number of birds an area can tolerate, the most important factors to consider are soil type, drainage, flock size and frequency of rotation. Fewer birds can be raised on heavy, poorly drained soils than on light and well-drained soils.
