Introducing a new chin?

[KiteKatsumi]

I've owned a chinchilla for about a year now. She's a roughly 2 year old female and I was hoping I could get her a friend since the person I bought her from was a breeder and always kept her with other chins. I was going to buy another from that breeder (a baby) but a week before it was old enough to leave its mom, its mom killed it and partially cannibalized it...so that didn't work out :/ That particular breeder decided to sell his chins and cease breeding shortly after.
I was wondering what the best way is to introduce a new chinchilla to Furby. The breeder said to spray their butts with perfume so they smell the same and won't fight...is that really a good idea? Also, would it be safe to put a baby in with my adult, or would it be better to purchase another adult? Should they be introduced on neutral ground?
I decided to come here rather than looking it up in my chinchilla care book, since someone told me not to trust it and suggested I come here.

The first thing you will need to do is to quarantine your new chin for thirty days. That means, you need to keep it in a separate cage and a separate room for that time. You should wash your hands anytime you go from one chin to the other.

After that you can place their cages side by side for at least a week, longer if they are still trying to get at each other through the bars. Then, you can try swapping cages every day or two for a couple of weeks. This allows them to get used to each other's smell.

The next step is allowing them to meet each other in a neutral area. That can be a new cage, the bathroom, if that isn't the place where your first chin has been playing, or a cage that has been cleaned really well and rearranged. There may be some dominance humping, sniffing, chasing, barking and even a little fur pulling. As long as no one is being aggressive, everything is fine. Separate them if they get too aggressive. By this I mean biting, violent chasing attacking each other, etc. Try to end this first meeting on a good note and then put them back in their cages. Do this several times, lengthening the time each time.

Once they get past this stage, you can put them in a cage together, but keep a a very close eye on them. Separate them if they show signs of aggression. Do not leave them alone overnight until you are sure that they are okay with each other.

This process can take awhile (weeks or even months). What ever you do, don't rush things. Rushing things can lead to disaster.

Good luck.
