Aww I think she just wants to be let out of her cage. I'd put all things that comfort her, such as items with her smell on, a toy, and some delicious food in her cage and leave the door open, she will come out to play but when she's hungry, she'll go in her cage to eat and after food they nap usually so allow her free range for time then place her in her cage to sleep and eat and she'll soon go in her cage of her own accord when she gets used to it. But I wouldn't let her be locked in for the most part as that will make her unhappy. Buns tend to sleep in the daytime and eat/play/come to life more at dusk and dawn, so at sleepy times put her in the cage so she can feel safe while she sleeps then defo let her out in the mornings for some good play time and also at tea-time for a good few hours, then pop her back in. She'll soon get used to her new environment and the cage being her safe haven, and will eventually enjoy the cosiness of her cage, yet you do have to allow lots of free range time too as otherwise she'll be sad being locked up. My rabbits cage is my full bedroom. He tends to sleep on the floor but he does jump up onto our bed now and some mornings he's on the bed when I wake up or he wakes me up with his whiskers sniffing my face. He just wants to be close to his family (us) since his girly best friend just died several weeks ago. So now he needs his family by his side more than ever. Thankfully I'm home a lot but come this September, I'm gonna get him a new (rescue) bunny friend, since I'll be out a lot more and bunnies literally need some kind of company. They choose love over food anytime, even if they're starving, this applies to literally all buns which to me suggests ow deeply important it is for their well being that they have the presence of some type of company and for long periods or for life otherwise they get lonely and depressed being alone, with no company. So as we won't be around as much soon, he defo needs a pal to maintain his mental well being. So not only do they need a lot of space, they would definitely benefit in terms of mental (and physical, since they groom one another) well being having another friend around if you know you can't provide a lot of time yourself giving strokes and hugs and kisses and snugs and tons and tons of loves, then maybe a pal would be a good idea too if you can afford it. Bt if not, you're enough good company! If you do get a pal then I'd do that after spaying/neutering as this gives them a better chance of bonding lovingly w/o the sexual hormones raging lol
