This is completely normal. I have a great bond with my pair, but if I dare interrupt the “under the sofa digging time” I get growls and lunges. Then a few minutes later they let me pet them and they purr, it’s just their way of communicating ‘no’.
Bunnies like projects, mine are currently obsessed with getting on top of the computer processor to just sit there, that’s literally what they want do, and even though it’s all blocked off they will sit and stare at it from every angle before trying to find a way to jump/climb up or “dig” under (can’t dig up a hard floor but tell them that!). Blocking it off seems to make it more tempting for them to try and find a way in. They are quite smart and seem to enjoy a good challenge, and they usually find a way! Whenever I chase them away from here I also get the foot flicks of annoyance haha.
This is just bunny behaviour and you learn to love it, or tolerate it for the cuteness
Also, most bunnies never like being picked up.. ever. So don’t worry about that. Only pick her up when you have to, and don’t try and pick her up for cuddles because to pet her you should lie or sit on the floor with her, that’s what they like.
Whenever mine are hyper and in the crazy mood where all they want to do is dig and get into the blocked off areas, I just sit on the floor and they usually end up more curious about me instead, so they come over and I can pet them and that also calms them down.
