Domestic sheep reproduction - Wikipedia
Domesticated sheep are herd animals that are bred for agricultural trade. A flock of sheep is mated by a single ram, which has either been chosen by a farmer or, in feral populations, has established dominance through physical contests with other rams. [1] Sheep have a breeding season (tupping) in the autumn, though some can breed year-round. [1]
