Hello everyone. My month old male duckling is bleeding from his tail. I know it's not the best picture but it's all I could get. I have no idea what this is but I do know that the only animal that could have done this to him would be another duck (nothing with actual teeth or big claws). I've heard of blood feathers but I don't know much about them. This is right on the end of his body, a little above the vent.
