How do turkeys and guinea fowl distinguish males from females?

Generally, the anal inversion method is used to identify the sex of young turkeys. Identification method: the palm of the left hand clings to the little turkey and grabs the little turkey. The cloaca tilts upward to identify the person, and the right hand gently pulls the tail of the little turkey to the back to expose the cloaca. Two reddish oval globular protrusions can be seen in the lower part of cloaca, which are male chicks; There are no two protrusions on the lower part of the cloaca, but a pale pink splayed fold. The bottom is thickened and extends to both sides, and gradually becomes thinner. This is the female chick. However, the bulbous processes of a few male chicks are pale pink, and the splayed folds of a few female chicks are thick and nearly round, which is easy to cause misjudgment. When it is difficult to identify, you can gently touch the lower part of the cloaca with your fingers. Because the spherical protrusion of the cock is made of dense tissue, it is elastic and shiny, and it is not easy to deform after being touched, and it still remains spherical, while the splayed fold of the female chicken is made of loose tissue, which is inelastic and dull, and it is easy to deform and flatten when touched. According to this difference, men and women can be distinguished.
