A group of sheep is commonly referred to as a flock. This term is widely used in both everyday language and in agricultural contexts. A flock of sheep typically consists of a number of sheep that are kept, fed, and herded together. The size of a flock can vary greatly, from just a few sheep to several hundred or even thousands.
In addition to the term flock, there are other terms that can be used to describe a group of sheep, depending on the context. For example, a group of sheep that are being driven or herded by a shepherd is sometimes called a drove. Similarly, a group of sheep that are being raised for meat production might be referred to as a mob in some regions, particularly in Australia and New Zealand.
Understanding these terms can be helpful, especially if you are involved in farming, animal husbandry, or simply have an interest in the subject. The term flock remains the most commonly used and recognized term for a group of sheep.
