hi mate ,
what ever you do dont ever flick youre ferrets on the nose !!!
they are just playing , and a ferret should be youre best pall .
you mast keep on handeling them , if they bite to hard correct them bey talking harder and just say , no !!! olsow you can thake them by the back of there neck skin , they wil take it verry soon .
tip : frequently put a finger in there mouth .
so they wil get used to it .
handel them every day , and always treat them with love and respect .they wil treat you the same way back
