I have had my chinchilla, Blessing, for about 6 years and I really want to get her a friend, but I want to get a baby female chinchilla. Will they get along and be able to live together?

I’ve recently bought my chinchilla a flying saucer wheel but he doesn’t run on it. Every time he gets on it moves and he gets scared and jumps off. He’s 6 years old and has never had one before, will he get used to it or will he always be scared?

Did you have the same problem and how did you resolve it? Thanks.
