The more I learn, the more I realize how little I know
And so it is with the best of us! We are all learning new things every day. Chinchillas are fairly new to the pet world. For this reason, they are still a mystery in their own time. We know lots about them, but never as much as we need to know.
The two chinchilla kits shown below are the same age, born the same day, within minutes of each other ... and to the same mother ... they are littermates ... brother and sister. The size difference is due to superfoetation/superfetation. The brother was conceived before the sister, each in it's own uterus (horn). Female chinchillas have two uteri and two separate sets of teats. Good ole mother nature! You might want to check out:

You state:
our Mommy chin was a surprise acquisition, not really planned. She arrived with absolutely no background information. We have been wondering if there is any way to decipher her age. Other than delivering a healthy son since she moved in with us (so we know she is an adult) I have no clues.
Haven't been on for a while so, I don't know the background ... how was she a "surprise acquisition"?
Where did you get her? A friend? Add in the paper? Pet store?
How long did you have her before she gave birth to her son?
Actually giving birth to a kit does not mean she is an adult. "Adult chinchilla" usually means
1 year or older. Female chinchillas have the ability to get pregnant at 3 1/2 months of age (not a safe or smart thing to do, but possible). About 110 days to develop the kit/kits + 3 1/2 to 4 months of age = 7 to 8 months of age for the mother ... IF she got pregnant as soon as it is possible for one to do so.
Warning! Male chinchillas, at the tender age of 10 weeks, have the ability to impregnate a female. So, her son should be caged separately by the time he is 9 weeks old. Chinchillas do not make a difference as to who they mate with ... even if it is another family member. Mating within the family is/can be double trouble for the kits.
Weight ans size of a chinchilla will not give you it's age ... that, unfortunately , is impossible to know without getting the information from the Breeder. Most adult chinchillas loose that "baby look", but, as is the same with humans, some adults retain that 'baby look'. {In most chinchilla shows, chins are shown when they are considered in their prime - between 9 months and 2 years old. I attended one show, being judged by a seasoned judge that almost chose a chin to be #1 in it's class, but this chin was over 5 years old - some chins can fool the even the best! } Wish I could help your more there, but without the original information, it's impossible.
Most chinchillas need the same things ... good quality food, plenty of hay, fresh water daily, clean cages, a routine and lots of love ... the last listed is almost as important as the first.
For my herd, with hay, Timothy hay is the norm after the age of 6 months ... UNLESS, it is a female in breeding. I give my breeding females 1/2 Timothy and 1/2 Alfalfa hay. When nursing, I give them all Alfalfa ... the same with new kits until they are at least 3 months old, then I change them over to a 1/2 and 1/2 mix until they are 6 months old ... at 6 months they get all Timothy hay. The one thing about hay ... above anything else is that it is fresh, free of mold and does not have a sour smell to it. If in doubt ... throw it out! { & buy new fresh hay}
She is so very sweet, and getting sweeter every day. Someone must have loved her a great deal. I still wonder what could have happened to cause a loving chinMom or chinDad to give up such a beautiful baby .
Maybe someone handled it to roughly and it bit them in self-defence. If the one bitten was a child ... maybe the adult didn't know it was the child's fault and they got rid of the chin thinking it was dangerous. Maybe the owner passed away. Maybe the owner just didn't have enough time to give the chin proper time and love and gave it up for that reason. You never know.
Hope this helps a little ... remember ... if the male kit is still with it's mom after it is 10 weeks old ... he can get her pregnant, please house them separately before he is 10 weeks old.
Keep us posted!
