What are the small sheds in a horse pasture?

The small sheds in a horse pasture, often referred to as run-in sheds or shelters, provide a protected area for horses to escape harsh weather conditions such as rain, wind, or extreme sun. These structures allow horses to rest and seek refuge while still having access to the pasture for grazing and movement. They are typically open on one or more sides, allowing for easy entry and exit, and are designed to ensure the safety and comfort of the animals.
