I know its tempting as they're so adorable, but you may still get to enjoy him or her, but the rabbit will be happier in the wild where they belong. If it's a female and its safe there you may find she/or her mother may come back to nest there yearly. I know in our previous home we had a mother rabbit that was very kind in having babies in our backyard yearly even twice a year, so we got to see them leave the nest if we were lucky enough to be home when they went. And it was awesome BC for whatever reason she had a white diamond on her forehead. I hope you get to see the baby all grown up.
