I agree that maybe she is overwhelmed and intimidated by the vast space and change that is suddenly upon her. Give her a smaller space to call her own and let her grow to feel secure in that and then open up more space to her. Of course, I already can guess that she would still need enough space for proper excerise and playtime, even if she is doing it all solo for a while until she begins to feel safe in her environment. Also, while she is feeling things out on her own terms, let her come to you.. as she begins to feel more trusting and secure, her curiosity of the person who keeps giving me all these yummy goodies to eat will kick in and she will decide to try to check you out. Also, I am unsure how often you put her on the bed, but try to maybe pick her up less. Come down to her level on the floor with her… she may be still very unsure of you and doesn’t really love feeling so vulnerable being picked up.
When I adopted BunBun, (she was being rehomed by a family that was ready to put her in a shelter) she came with a cage that I had no choice but to pick her up in order to get her in and out of, and when I finally was able to rid of that and got her a crate (her diva den domain), she improved quite instantly simply because she was then able to get in and out on her own, without be mom-handled.
