I found this young Whitewing Dove on the side of the road. No visible injuries, but his head was drooping and he is disoriented. I rehydrated him, and have been hand feeding him. I have attached pictures. His poops are a little on the yellow side, but not bad. He shows all the signs, to me, of PMV. Head drooping sideways and hanging low, and when he isn't doing that, he is stargazing. He tries to fly, but only goes in crazy circles. What do you think? I know he may have been hit by a car and has internal injuries, but I see no signs of that.
