I dont want to make light of your situation, even though my gut feeling is that Daisy has a great life. Does Daisy have enough room to do binkies? Rabbits need more space than previously believed, at least for some part of the day. Binkies aren’t absolutely required -for bun happiness – sometimes they’re even a sign of stress. Its a lot more important that the bun can relax in the presence of their human.
Do you have other pets (f ex a dog) that Daisy might perceive as a possible threat? Dogs can be totally complacent and calm and the bun can still need quite some time to decide that the dog is harmless.
It’s normal for adult (i e post-babyhood) buns to be shy around other people than the primary caregiver (you). Some buns are more outgoing than others, but as a rule, rabbits aren’t trusting of strangers and semi-strangers. Normally they will gradually accept other people over time, but they tend to do so very slowly (years, often several years). I recently read about a 9 year old bun who suddenly decided to jump into the owner’s lap and demsnd pets. If your bun is attached to you, chances are good she’ll eventually accept other humans as well.
It’s good to keep an eye on food intake, poop output and body weight. You could perhaps weigh her once per week and write her weight down in a weight-journal. I always recommend keeping a health-journal for everybun, because its pretty much not possible to keep score in your head.
