Hi,I'm a chinchilla pet owner from Portugal so I apologize in advance for any english mistakes.
In the past year I've bought a male chinchilla and recently I decided to get another one,so I bought his brother.
They're about 1 year old.
I keep them in separate cages that are now really close to each other.They seem okay,however some times the new chinchilla "barks" at the other one.
I've tried to let them out for their daily walk together,but it didn't really work well.They chase after each other and make kind of barking noises,they also seem to "nose fight"(they stand in front of each other and move their noses in circles).
They don't bite each other and there's also not hair pulling.
What should I do now?Are their behaviours normal?Are they just trying to figure out who's the dominant one?
