Ducklings can also eat anything on this list as long as the treat can be cut into very small pieces or is soft or mushy to prevent choking. The sooner you introduce baby ducks to a variety of foods, the more accepting they will be and the more apt to try new treats.
Abnormal blood clotting: Anything that interferes with blood clotting can lead to nosebleeds. Medications, even common ones like aspirin, can alter the blood-clotting mechanism just enough to cause bleeding. Blood diseases, such as hemophilia, also can provoke nosebleeds.
Inability of the blood to clot is most often due to blood-thinning drugs such as warfarin (Coumadin) or aspirin. Liver disease can also interfere with blood clotting. Abnormal blood vessels or cancers in the nose are rare causes of nosebleeds.
