Rescued???

Jeff was driving home late one night and "rescued" 2 dove that had been "wing shot". We had a heck of a time getting them out of his truck, being there were plenty of areas to hide.  We have been feeding and watering them, unfortunately we lost one and am now down to the last one, it was not hurt as bad as the first and we are hoping that it will be ready to be set free soon. I any one has any advice please let us know.
