a herd of sheep that are cared for and pastured together. The animals in a flock are homogeneous in sex, age, and pedigree.
A flock of fine-wooled or semi-fine-wooled ewes contains from 600 to 700 head. Semi-coarse-wooled and coarse-wooled ewes are kept in flocks of 700 to 800 individuals. Flocks of rams raised for breeding purposes contain up to 200 head. Sheep pastured for fattening and wethers are in flocks made up of 900 or more individuals. Female lambs between four and 18 months of age are kept in flocks of 700 to 900 head. In steppe regions larger flocks are sometimes formed, and in central and northern regions somewhat smaller ones. On sheep-breeding farms the flocks are 15 to 20 percent smaller than those on commercial farms. A flock is tended by three or four shepherds.
