Yes, patience patience! And remember, if you go for trying to grab her and she huffs, hisses, etc. DO NOT PUT HER DOWN! She will just learn that doing that will get her what she wants (you to back off, and her to stay in her cage.) If my girl is in a bad mood, whether it is quilling or she's just having a grumpy day, I still sometimes have to mentally tell myself not to give into her. Don't be afraid to pick her up with fleece until you are comfortable holding her! Just don't use gloves, it will mask the scent of your hands. Also, learn how to reward her for being a good girl with bonding time.
I hope some of that was new information! Good luck, keep us posted.
