Answer:
A young ferret needs to be properly socialized and requires quite a bit of human interaction and playtime. Baby ferrets play together by biting each other. Is your ferret wanting more attention or just wanting to play with you. You teach a young ferret not to bite by scruffing, which is the way the mother ferret scolds her babies. When your ferret nips or bites, scruff him/her (gently grab the skin on the back of the neck with your thumb and forefinger (or index finger) and lift up a little and your ferret should relax, while saving "No" in an authorative voice. Never hit or flick your ferrets nose, as they don't understand that action.
