Introducing a new ferret, encountering what looks like extreme aggression... Any thoughts?

its best to let them play together in a neutral setting like a bathtub.... where either one doesnt have their scent the male is going to be dominant to the female and is just trying to show her... this is my house... you listen to me sometimes getting the male neutered will help the problem if they get along well reward them both and in no time theyll be playing together
