Can a baby blue jay that has been hand raised be released?

my daughter found a baby blue jay in our yard last week. the poor thing must have fallen from it's nest, and was completely covered in ants. it's hard for me to imagine, but if she hadn't found it, i'm sure the ants would have eaten it, even though it was still alive. after getting the ants off of it she brought it inside. we looked in the trees where she found the baby, but unfortunately we didn't see a nest. i bought some kaytee bird formula and have been feeding it according to the directions. the baby bird seems to really be flourishing. i'm hoping it will make it. will we be able to eventually release the bird back outside, or will it be too used to humans? my fear is that if we let it go, it won't be "afraid" of humans or other animals, and something will happen to it. has anyone ever had this experience? if so, any advice or suggestions would very much be appreciated. i don't know of any wild life sanctuarys close to us. also, when should we start to feed the baby bird other things? what else do blue jays eat? thank you.
