I have a female, beige chinchilla who is 4 years old. I want to breed her eventually (within the next year) but I don't know if she's too old to start breeding now. She's never been bred before, but I feel like she would be a rather good mom. She has no health problems and is pedigreed so I'm not worried about that side of it. Just wondering if I would need to get another, younger female to start breeding.
