Why do chickens and roosters need a comb on their heads? The comb not only shows the attractiveness of the male to the female, but also the state of his health. Scientists have found that in healthy roosters, the comb is large and has a bright color. In sick birds, the comb becomes smaller and paler. Perhaps the same property is characteristic of other birds. If so, then the decorations on the body of animals are not just for beauty, but show the health of the male. 💪
