I know it's a long way, but something to think about..

In the next year or 2 I am going to get another chinnie I am excited, but it's stilla long time. I would put him with my male chinchilla. I have a double unit critter nation. I have A castrated male with a female in the lower section and my male in the upper. If I got another male chinchilla and he went in the top section with my other male, would they be prone to fighting since they can smell the female below? Should I risk the fighting and get a mle or should I castrate my other boy and get a female?

I have several long time male-male pairs and trios in the chinchilla room right below, next to or above cages with females that are in breeding. It doesn't cause them to fight if a female goes into heat next to them. They fight when a female goes into heat that they can physically see and think they can get to, to mate. That triggers their need to compete for her and starts the fighting.

i have two males (father and son) together in a FN cage now, next to that cage is another FN cage with a female and two daughters. With the sides of the female cage obstructed so the genders cant see each other.

I can defenitly say dispite not being able to see each other, my father chin still goes nuts over the female. Se will get as close to their cage as he can can sit their forever. Other time he start screaming in that same spot. He wants at her bad. It even got to the point where if he saw her when she was out for play time and he was in his cage, he would go so crazy it lead to seizures. So needless to say, they are never allowed to see each other any more at any time. (However, to date, the two males have never started fighting with each other)

As for yours, theirs no gaurentee that another new male would get along with yours. Or that they would one day have a fight and need seperating. Without some where to house him seperetly i wouldnt try it.

But if you already have a fixed male, and a female, then why not let them be cage mates?
