Several months back I had a stray white ringneck dove show up while I was out feeding the chickens. It had been hit by a hawk and practically scalped, but was okay otherwise. Since then I got it a cage, read up on what to feed it and how to care for it. Now I have a happy, healthy dove, but no idea whether it's male or female, and would like to get it a companion. It's very vocal, cooing on and off all day, so I'm thinking it's possibly male (we call it "he" at this point), but I'm wondering is there's any other way to tell the difference between the two? I'd hate to get another male and have them end up fighting.
