What age can they have wheels?

[Mookie]

I was wondering, what age is a good age to let your chinchillas have a wheel in their cage?

Usually I see people say not before 6 months.

Half my adult chins don't have wheels for certain reasons. It is suggested that chins under 6 months not get a wheel because they need all those extra calories they'd burn off on their wheel for growth and development.
