My parents have a pet mourning dove named Cocoa that they have had for about 10 years. He is even older than that - some friends of ours rescued him from the mouth of their cat and rehabilitated him. However, one of his wings was dislocated or something (it just hangs down, and he really can't use it at all), so they kept him in a cage for a couple years before the husband forced his wife to get rid of it after finding out they can live to be 30! (He hated the "hoo-ing" sound they make, which I find so weird because most people think it is so pretty!) So that is when my parents took him. All this time he has been alone, but I am wondering if he would be happier with a friend... any thoughts? He has been a temporary pal to a number of injured/baby poultry and birds who come into the house for special care (cages side by side), and always seems to enjoy that, but has never had a long term cage mate. Would it be a good idea for me to encourage my parents to get him a friend, or at that point is it really not needed? What got me thinking was I got some roller pigeons and they are not much bigger than Cocoa.
