Call your nearest WILDLIFE RESCUE ORGANIZATION. It will be difficult letting her go, but she can be gradually trained to live in the wild--- great people will take care of her and she'll be able to associate with other deer buddies-- and hopefully have her own babies soon! Best to you, and God bless you for being a great "mommy" to your little doe!!
A wildlife organization may be able to wild her up. Where I live in Virginia it's illegal to rehab deer fawns in one city and release them in another. Chronic Wasting Disease is the reason. When she comes into season you may have some bucks showing up...and you don't want that. (hunters need not reply) lol
