We have a lone collared dove who flew in one day and kept landing on our heads, so obviously not wild. She lives in our aviary with finches and bourkes parakeets and seems happy. She makes a nest constantly and sits on her infertile eggs. She's still very friendly and sweet. If you are home all day to be companion to your dove it should be happy enough, but if not a friend would be preferable. Some doves can cross breed but it's not ideal so it's best to remove fertile eggs and replace with dummy eggs (make some out of polymer clay) otherwise you'll have too many doves and no where to put them. They are very prolific! Make sure you get a dove of similar size as larger 'doves' (ie. pigeons) can bully smaller doves, and some doves are tiny, such as diamond doves.
