Domestic horses, also known as Equus caballus, display multiple behaviors based on the conditions they are exposed to. Horses tend to graze for long periods of time throughout the day (Goodwin 2010), and their environment has a major impact on the way they tend to graze (Lewis 1989). In warmer weather, the horses graze in various spots on a field in comparison to colder weather, where horses huddle up and graze in a couple of selected spots. It's estimated they graze about 15-17 hours per day (Sharon 1986). Horses tend to “stick together” and live in groups (Lansberg 2018), as horses feel more protected in these settings due to having more companions that are willing to look out for predators and food. This ultimately results in a greater chance of survival. Groups also allow a source of protection for one's resources such as: food, water, and territory. A common behavior that has been observed amongst young “colts” or male horses, is that they tend to follow the older horses within the pack (Hill 2010). This behavior allows colts to learn behaviors from their older peers while at an early age. These examples demonstrate that depending on their surroundings, domestic horses behave differently based on their environment and what stimuli they are exposed to.

Suggestion
The scientific name for domestic horses, "Equus caballus" should be italicized.
Suggestion
I don't think you need quotations for "stick together" or "colts," quotes are almost never used in scientific writing.
Horses live in herds, not
Horses live in herds, not packs. Also your last statement is a little vague and redundant.
