My rabbits HATE the outdoors. They get free run of the apartment and are offered leash time outdoors. My male does spend some time on the balcony (don't worry, it's 100% enclosed), but every time her hears a person (which is often), he freaks out and wants inside. My rabbits would NOT do well outdoors, since they are definitely indoor bunnies (sort of like outdoor vs. indoor cats). They do, however, get free run of the apartment when we are home to supervise, and access to look out a window when we are not. I think it depends on the rabbit. Even my female, who is fine with wearing her harness inside and LOVES going to the vet/events where she is inside, does not like how 'dirty' the outside world is (she literally just cleans her feet every time we go out ).
