How much approximately should a female chinchilla weigh before and after giving birth? I know there is fluctuation but what would be a dangerously low post-birth weight? I know absolutely nothing about breeding and am trying to help a friend. I do not want to give the wrong advice. I believe the female who gave birth unexpectedly is quite small and I do not know if I should advise handfeeding or not. I have already told him to carefully monitor food and water intake, remove treats, and to weigh her regularly as well as the one kit. The kit is doing quite well and now weighs 64 grams I just worry about the mom.
