HELP!! Violent ferret introduction

Question
I just recently brought a young ferret kit home to my 2 other ferrets Stinky, and Pookie.
 Pookie is being very violent towards my new (unnamed at this point) ferret.  Pookie will repeatedly chase down the new guy and grab him by the neck and shake him around like a rabid dog, and drag him across the floor.  He shakes more, and when he shakes the new guy hew makes a growling noise like a cat would in a fight.  I have given it 3 days because people say it will ususally get better, but in this case it's not--may be getting worse.  The new guy is getting sores and scabs on his neck, and last night while getting attacked he pooped all over the floor. So untill I get help they will be seperated, because I cant let this continue.
 FYI-- Pookie is 2 yrs old, my other one Stinky is the same age, they are both males.  They are friendly with eachother, and Stinky likes and plays with they new guy.

It is so bad that the new guy runs in fear at the sight of Pookie, and I have tried Dragging and hissing at Pookie when the attacks happen and it hasn't helped.

I have had the new guy for 4 days now.

Please Help!!!

Answer
There are a couple of things that could be happening. First, it could be that Pookie just doesn't like this new ferret. Ferrets generally are very social animals and love everybody, but for some reason or another, you will come across a ferret who just doesn't like somebody else. If this is the case there isn't much you can do but keep them separated or maybe find the new ferret a new home and try again with a different ferret.

Secondly, it may be that Pookie is just integrating the new ferret into his pecking order. New ferrets and established ferrets always "fight" it out to see who's the boss; it's nothing to be alarmed about as long as they're not drawing blood. But the fact that he's pooping is bothersome, it sounds like he's really scared. Keep an eye on them. If within a week or so it's not lessening up, it may not be a good match. Fighting for dominance can last weeks to months, but it usually is less intense over time.
