I wish I would have seen this yesterday. I am sorry that Dr. Debbie hasn't been on so if you do not mind I would like to respond for the bunnies health. This little one was likely out there learning the ropes like the rest of the clan. Mom probably wasn't too far away. Most wild rabbits do not survive in capitivity and given her size she really needs to get back out there as close to where you found her so mom can take her back in. It is okay mom won't reject her because of your scent. It is also very possible that this baby is ready to be on her own. If she only has a very small white dot on her head or no white dot at all she needs to be released. The best thing you can do for this little one is either release her as close to where you found her or look for the nest under some brush or bushes. Again most baby bunnies do not survive in captivity.
