It takes 11 months for a foal to be born. In their second year, a male is called a colt. A female is called a filly. They are also called yearlings. It takes four to seven years for a colt to become full grown.
Wild horses eat grass and other plants.
They drink water from seeps, springs, streams, or lakes. Adults eat about 20 pounds of plant food each day. Each band of horses has a lead female called a mare. The mare leads the family to food and water. Wild horses may roam many miles to find food, water, and shelter.
