A young horse is called a foal. Foals are typically born in the spring months and are highly energetic and playful, learning to walk and run shortly after birth. They rely on their mothers, or mares, for nourishment and care during their early months. Foals are eventually weaned and can be trained for various purposes, such as riding, racing, or work. The term "foal" usually refers to horses up to one year old, after which they are classified as yearlings. Understanding the early stages of a foal's development is essential for proper care and training.
