Help on my rabbit pls?

[Glamorris]

I have adopted a female cross breed rabbit. The past owner said that she's about a year old. She looks quite like a full grown rabbit already. I know that the rabbits will be scared for about a week or two as I have a male rabbit and i've had it since it was about 6 months old. However, she seems to be always afraid of me. She's always backing away and hiding from me even though i've had her for about 4 months now. It took me 6 months to fully bond with my male rabbit but even though it was that long, he was not that afraid of me after two months and comes to me sometimes when i call his name. What do you all think I can do to make her less frightened of me?
