I have seen before that if it can walk/fly/swim let it be but this duck is NOT able to fly or swim. I watched it for a while after hearing its cries. Its leg is extremely messed up. She is not able to walk on it she can barely move around. Her wings are a little underdeveloped but she is full-grown/full-sized but her wings are nubs she has no flight wings or any wings. The Feathers on her head are falling off (they may have been plucked out) I don't know what I should do. I LOVE ducks and I hate to see them in pain. Its a female mallard.
