Sexing 1 day old chinchilla kits

It's actually quite easy determining the gender of very young chinchilla kits.
The first couple of times can be a problem, but it becomes easier with time. The best reference is when you've seen both a young male and female.

 

As seen above, the male has some space between the anus and genitalia,  whereas there's no space when it's a female. Chances are it's a female, if you are not quite sure about what you are looking at.

If in doubt, wait a couple of days or a week, then there shouldn't be anything to mistake.

In adult animals, the difference becomes more evident. When the male becomes sexually mature his testicles will fall down, giving the impression he has some excess skin around his genitalia and anus.


Even though it should be quite easy to tell the sex after a couple of litters, every body can make mistakes. Therefore; be sure to check the gender around 10 weeks, because some animals do become sexually mature here. You should also check the gender yourself, when buying a chinchilla, and not only rely on what the breeder tells you.
