IMO ... you are doing everything right so far. Giving her space and time and respecting her growls and warnings. Thats all you can really do. Its only been 2 days. This could take days, weeks even months for her to adjust and feel safe and secure. I say, continue to talk softly to her about everything and anything. See if you can get her to play the whistle game with you or mimic her whistles (when or if she does them) Alot of time they say if your fid sees you playing with something they will become inquisitive and have to have it too so you might show her "toys" or treats then keep it to yourself and see if that sparks her interest to see "whatcha got" Relax and enjoy having your new baby home and follow her lead!
