Hello, and welcome to the forums (and bunny parenthood!). Buns can be a bit unpredictable. Not wanting to be picked up or held isn’t uncommon. Of course, it’s confusing for you because she didn’t mind it before, but now she does. I’ve found they often change their minds about things, it’s just their nature. The one thing I wouldn’t do is try to force the issue. Assuming she can get out of the cage on her own through a floor level door, I think the best approach would be to open the door while you’re in the room and let her decide when she wants to come out and interact. Let her come to you and sniff around so that she’s gets comfortable interacting with you. Take it slow and go from there. Also, has she been to see a vet yet? If she otherwise seems healthy, then it’s probably just a change in her temperament, but sometimes big changes in behavior can be health related. I’m no expert by any means so keep checking this thread for other suggestions.
