How Big Is A Herd Of Horses?

In a wild or feral state, herds of horses will roam across wide areas of land. It is not uncommon for two or more herds to co-exist in the same area or territory, but they will rarely cross paths or interact with each other.

A herd of wild horses is normally made up of one or two stallions. The herd will also have a group of mares and their young offspring.

The size of a herd of horses varies widely, according to their physical terrain and social dynamics. There are normally around 8 mares per stallion, plus their offspring. This means that a herd could be made up of around 20 horses.

Horse Group Dynamics Explained

The way a herd of horses interacts is fascinating! They have a complicated social structure, with each horse playing a different role. Let’s take a look at how the dynamics of a herd of wild horses works:

  • The Stallion

The entire male horse, or stallion, is the protector and guardian of the herd. They also have a key role in reproduction, impregnating the mares during the breeding season.

The stallion has to constantly battle to keep his place within the herd. During the breeding season, he will face threats from other stallions wishing to take his place. If he gets ousted from the herd, he will seek to take over a new herd or join a bachelor group.

Most stallions remain part of a herd for about two years. In some cases, they can last for over ten years as herd protectors and guardians.

  • The Alpha Mare

The alpha mare is the leader of the herd. It is unusual for the alpha mare to be replaced, and she will remain with the herd throughout her life.

She is normally an older mare, with a lot of experience and dominant nature. The alpha mare is not always the strongest or biggest female in the herd, but she will be the one who makes decisions and keeps the herd in check.

In a domesticated situation, you will find that one mare will quickly become the alpha mare in your paddock. She will dictate when and where the other horses graze, sleep and relax.

  • Colts

As there are only one or two stallions in each herd of horses, colt foals are not permitted to stay in the herd once they become old enough to survive on their own. They will leave the herd and form a group of horses made up entirely of males. This is called a bachelor herd.

  • Fillies

Young female horses are not always ousted from the herd, and some will stay in the same herd as their dam. This is not always a problem, as it is likely that the stallion will be replaced at some point so she will not be impregnated by her sire.


More commonly, fillies will leave their birth herd and join another herd of horses. They may also join up with an entire male from the bachelor herd, forming an entirely new herd of horses.


So, as we’ve learned, the name for a group of horses living naturally in the wild is a herd. Groups of domesticated horses can also be referred to as teams, studs, rags, as well as several other names. In the wild, a herd of horses has a complicated and intricate social structure, with herd dynamics changing constantly.
