Congrats on your new chinchilla! I got my chin over a year ago. My chinchilla, Moxie doesn't like being grabbed to be picked up. She likes to come to you and then you can pick her up. Don't rush into grabbing your chinchilla, just give it time and let your chin come to you. Also be very careful about the way you hold them. Do NOT squeeze the chinchilla as their ribs are as fragile as toothpicks and they can break pretty easily. However do not be afraid of holding them because they won't get hurt u less you squeeze them.
if you do get another chinchilla, be careful because you can't put them instantly together in a cage. You have to slowly introduce them in a big room so they can meet peacefully without being locked together. I strongly suggest getting the same gender to avoid mating. Also introducing them takes a while and takes patience, over a few days time until they are comfortable with each other. Don't feel discouraged if they do not like each other at first because it does take time.
If you have any other questions ask away, because even though I am new to the forum I am not new with chinchillas and I have a good expirience with them. Hope this helped
