What are the reasons breeding ducks need proper grazing?

After ducklings are raised to 30 days of age, proper grazing begins. Proper grazing for breeding ducks helps strengthen exercise, promote the development of the ducks' bones and muscles, and prevent them from becoming overweight. Herd the ducks into movement inside the house at fixed times each day, 5 minutes to 8 minutes each time, 2 to 3 times a day. Where conditions allow, short-distance, short-duration grazing can be done. This can help increase the ducks' boldness, prevent flock panic, and strengthen their physique and ability to adapt to the environment. Before grazing, artificial heating must be stopped so the flock gradually adapts to the outside temperature. At the beginning, grazing time should be short, then gradually extended to 5 to 6 hours per day.
