Alright, here is an update. She has started to eat the pellets and the treats I finally convinced my father that more then 1 treat a day is really bad. Had to show him why it is bad and vet info about it. She gets 1, maybe 2 pieces of papaya a day or a raisin. Only started giving her treats again when she was eating the pellets and the hay/alfalfa again. She actually has warmed up ALOT since we brought her home, she was actually a little fearful of women when we got her and when I opened the cage at the owners house she came right over and climbed on me. She is doing that again and has taking a liking to my mom, she rings the bell in her cage for my mom to come in and give her scritch's and she really gets into them to the point of rolling onto her side and showing her belly to get it scratched, actually a cute/funny sight. She loves everyone and everything but for some reason she just hated my dad from the beginning but now that I have him backing off a bit and only talking to her unless she comes to the front of the cage she has stopped barking at him when he gets near the cage. She still hates to be picked up but I expect that, I only pick her up when she literally leans out and puts her paws up my chest and sniffs my chin. Sorry for so much with little spacing but working on a few final papers, homework I missed, and trying to watch and talk to both chinchilla's so I know they arn't pissing all over eachother in there cages, to the point where the cages are close so they can sniff but not bite.
Thank you for the responses.
