This can make her very hostile and unpredictable which can be unhealthy to the baby ferret. A typical litter of ferret babies or kits as they are known ranges from 5 to 8 babies in general. They are born both blind and hairless which means that for all intents or purposes that they are helpless. After about 3 weeks their eyes will begin to open and their hair will begin to grow.
