Hello,

Such humping is most often a signal of domination. Many animals, both male and female, will do this to an animal they view as a subordinate. Your younger chinchillas are most likely in distress from the constant bullying. I would separate the chinchillas. Such problems are common when several males are kept together, and they will probably always have to be kept apart.

While it isn't common, some people do neuter male chinchillas. That would take care of the problem. You can read more about the pros and cons, the procedure itself, and the care that is involved at the following site:

If you decide to look into that option, you'll want to find an experienced chinchilla vet. This link will take you to a directory of chinchilla vets:
