What is a female donkey referred to as?

A female donkey is referred to as a "jenny." The term "jenny" specifically denotes a female donkey, helping to distinguish it from males, which are called "jacks." The term "jennet" is sometimes used, but it is not the standard term and can lead to confusion. A "jack" denotes a male donkey, while a "colt" refers to a young male horse or occasionally a young donkey but does not apply to females at all. Thus, "jenny" is the universally accepted term for a female donkey, making it the correct choice.
