from what ive read (so im probably wrong) what you need to look for is a bunny that has been handled by humans from before 5 weeks old... i have a feeling that my lop who is super chilled and friendly (when hes in a good mood) was not handled at all before he came to me at 8 weeks and he really really really dont like humans picking him up, i ofcourse am pretty scared of the little bugga so have not really tried to get him used to being picked up as it takes ages for him to love me again whenever i do so we are both happier this way
