A baby horse is called a foal. Foals are born after a gestation period of about 11 months, and they typically weigh around 100 pounds at birth. They are known for their long legs, large eyes, and soft, fluffy coats. Foals are able to stand and walk shortly after birth, which is crucial for their survival in the wild as they need to keep up with their mothers and the herd. After some time, usually around six months, a foal is weaned and transitions to solid food, and as they grow, they develop into yearlings before reaching adulthood.
