Just came home, to find my favorite duck has been injured by something or other....she has a fairly large cut on her chest, that seems to have stopped bleeding, however is breathing heavily. She's drinking and when I just went to check on her was standing in her water dish, but sounds horrible. When I carried her in there was some sort of almost clicking in her chest as she was breathing. What would you guess her chances of survival are? I don't want to torture her by keeping her alive, however she's my favorite duck and am sick about it...is there anything I can do?
