This afternoon one of my birds had this little hole in his beak. It looks like it also bleed from his nose. I have two parrots and honestly I don't know what happened. I put them both to eat in the top of their cage (they were free). And 20 min later I saw his nose. I didnt hear them fight or anything. Does it seem like the other bird did this to him? Or like he hurt himself while being free around the room? He has been eating good.
