Filly
A filly is a female horse that is too young to be called a mare. There are two specific definitions in use:
- In most cases, a filly is a female horse under four years old.
- In some nations, such as the United Kingdom and the United States, the world of horse racing sets the cutoff age for fillies as five.[1][2]
