My duckling has an underbite. I don't think she has any nostrals anymore either. She is a week and two days old. She started out fine and with in a couple of days i noticed she wasn't clearing her nostrals under water like thier suppose to. Then just in the past couple of days it has progressed to no nostrals and the top of her bill is groing widder but not longer, so now she has an underbite. She breaths with her bill open. I have told myself she isn't going to make it, am i right? She also has a funny colour on her bill, like a bluish purple so i think she isn't getting enough oxygen. I know what some people would tell me what to do wigh this little girl but i can't bring myself to doing that. I've worked realy hard bringing these little call ducks into the world and i'm hopeing i'm wrong about her. I've got children and grandchildren with asthma and i would never think of putting them out of thier misery. thanks in advance, Angie. I am going to try to get a pic of her without stressing her out cause then she has a hard time breathing.
