I found a baby mourning dove from my parents vaction home and I've been feeding it seeds but i dont know if i should. Can anyone tell me what i should feed it and how to make the food and also how i should take care of it. I have already talk to the animal people they said that if i give the baby to them they'll propbly have to put it down so i want to keep it and raise it.
