Ducks usually laid eggs that year. Generally, ducklings hatched in spring and summer will mature after being raised for more than eight months, and the mother duck needs to be supplemented with nutrition before laying eggs. Ducks also need proper exercise and careful feeding to lay eggs. Keep more drakes in the flock, generally increasing by 2%-3% according to the normal male-female ratio. The male duck's sexual stimulation to the female duck can make the female duck ovulate faster, thus making the female duck lay more eggs.
