(1) Exercise to observe whether the ducklings are lively and love to walk, whether they are in good mental state, whether they are listless, dozing off, crawling, hiding in the corner and behaving abnormally.
(2) Breathe to see if the ducklings have symptoms of respiratory infection, such as sneezing, breathing with the mouth open, mucus or serous secretions in the nostrils, etc.
(3) The feet of ducklings with normal dehydration degree are full and shiny. If there are wrinkles and shrinkage, it means that the duckling has been dehydrated.
(4) Check the disability to see if ducks have crutches, blindness and congenital and acquired disabilities, so as to be eliminated as soon as possible.
(5) Ducks are evenly distributed. If there is "crowding", it means that the temperature in the brooding room is too low, so the temperature in the shed should be increased; If the duckling is far away from the heat source, the temperature is too high.
(6) Ducks drink a lot of water quickly, which may be caused by hot weather, severe dehydration or acute infection on the way; The feed intake speed (that is, the feed intake of ducklings in a certain period of time) directly reflects the health status of ducklings. When observing the water consumption of ducks, pay attention to the reaction of ducklings to drinking water and feed. Good drinking water indicates the health of ducks.
(7) Digestion, observing whether the ducklings have omphalitis, whether the feces are shaped, and whether there is diarrhea.
