Pecking Order?

Question
I have three ferrets.  One 1yr old male, one 10mon female and one 4-6mon male.  The newest one, Leo is the youngest and we got him about 2 1/2 months ago.  The eldest male, jack, will not be nice to him.  When we first brought him home, jack bit his neck hard and would drag him around, which my boyfriend and I supervised and broke up when leo got stressed out.  But then it got to the point when jack just would not let go.  He would clamp down on leo neck and we would have to pry his jaw open, which worries me, I dont want to hurt him.  So over the next month we have had little playtimes with one of us always holding jack.  when jack manages to get away he just beats the crap out of leo.  Leo is a marshall ferret and now is big, but is just such a sissy.  They still dont get along, they cannot play together because jack just wont stop biting him and not letting go for the life of him.  The female get double play time because she gets along with both of them.  Ive switched the beds, washed them all so the scent is less.  Ive tried almost everything I know.  I just would really like ANY advice on how to get them to coexist.  Please, how do I get my ferrets to accept each other?

Answer
Something you need to understand about ferrets: they usually ALWAYS develop some sort of pecking order amongst themselves, especially between males it seems. There is no way around this, it needs to be done. As the older, established male, Jack feels he must dominate and protect his position against the new comer. Believe it or not, your ferrets ARE getting along, they are just feeling each other out. Part of this is rough playing and wrestling, which Jack will be sure to end with an "I'm the king" type of statement, which usually means biting Leo's neck and dragging  him around until he "surrenders" (yawns). Some ferrets are VERY stubborn, so he may need to hang on a while.

As long as there is NO screaming (very different and distinct from other ferret play noises), blood or pooping during this they are perfectly fine, you don't need to separate them. When I introduced Puppy to my group, Big Ferret (who was the dominant leader) immediately started playing rough with Puppy and biting his neck. But after a few months of that they started to just play and wrestle and have a great time together. So just leave them be, keep a watchful eye on them, but let them do their thing. It may take a while depending on how stubborn Leo and Jack are, but eventually they will establish their pecking order and be pals.
