Goals of Flock Management
A sheep farmer is concerned with keeping the correct ratio of male to female sheep, selecting traits for breeding, and controlling under-/over-breeding based on the size and genetic diversity of the flock. Other tasks include sheep shearing, crutching, and lambing the sheep.
Sheep breeders look for such traits in their flocks as high wool quality, consistent muscle development, quick conception rate (for females), multiple births, and quick physical development.
Sheep farmers also need to protect their livestock. Sheep have many natural enemies, such as coyotes (North America), foxes (Europe), dingoes (Australia), and dogs. Newborn lambs in pasture are particularly vulnerable, also falling prey to crows, eagles, and ravens. In addition, they are susceptible in some areas to flystrike which in itself has led to invention of practices such as mulesing.
Sheep may be kept in a fenced-in field or paddock. The farmer must ensure that the fences are maintained in order to prevent the sheep from wandering onto roads or neighbours' property. Alternatively, they may be "heafed" (trained to stay in a certain area without the need for fences). The hardy Herdwick breed is particularly known for its affinity for being heafed.
A shepherd and a Livestock guardian dog may be employed for protection of the flock. On large farms, dogs and riders on horseback or motorcycles may muster sheep.
Marking of sheep for identification purposes is often done by means of ear tags or ear marks. In some areas sheep are still identified through the use of notches cut in the ear known as ear marking, using either specially designed tools (ear marking pliers) or other cutting implements.

The flock of notes those antique negroes blew
Out of Chicago air into
A huge remembering pre-electric horn....”

National Forest, interested in fish,
Has mapped Tellico and Bald Rivers
And North River, with the tributaries

A fishy map for facile fishery....”
