About half of all wild horses are reddish brown in color. Others are grey, black, white, greyish-brown , and palomino colored. The final word, wild horses come in all colors. Wild horses eat grass or roughage and drink water from seeps, springs, streams, or lakes. Adults eat about 20 pounds of plant food each day.
Wild horses are able to process dry and course grasses and other vegetation.
They drink twice a day and also seek out needed mineral salt deposits. Wild horses can be separated into groups according to their age and gender. From birth to one year, both male and females are foals. In their second year, males are called a colt and a female becomes a filly. Colts and fillies are also called yearlings.
