How do ducklings divide the male and female pictures?

Ducklings are divided into males and females in terms of appearance, nostrils, voice movements, tail and neck. The picture is as follows:

1, shape

Judging the male and female by observing the shape of ducklings, the main characteristics of male ducks are large head, round body and pointed tail. Note that the male duck's jaw hair is pointed and irregular, and the female duck's head is small, her body is flat, her tail is scattered, and her jaw hair is neat.

2. Nose

You can also distinguish male ducks from female ducks by their nostrils. The male duck's nostrils are narrow and small, with linear nails along the muzzle, thick and hard nose base, and obvious ups and downs in the plane, while the female duck's nostrils are larger, nearly round, soft nose base and no ups and downs in the plane.

3, sound action

Judging the male and female by the sounds and movements of ducks, put the ducks in a bamboo frame one by one, and the female ducks keep jumping out of the frame. If the male ducks don't move. In addition, the female duck is hoarse when she is frightened, while the male duck is crisp.

4. Tail

We dragged the duck in our hands, pressed it gently on the duck's back with our thumb, and observed the state of the duck's tail. Generally speaking, a duck with its tail up is a female duck, while a duck with its tail down should be a male duck.

5. Neck

The necks of male ducks and female ducks are very different. When distinguishing the male from the female, you can gently pinch the duck's neck. If there is obvious graininess, the duck is a male duck and vice versa.
