What is a key characteristic of a properly formed "Horn" on a bird?

A key characteristic of a properly formed "Horn" on a bird is a smooth, even surface. This feature is crucial because it indicates that the horn is well-formed and healthy, contributing to the overall appearance of the bird. A smooth, even surface allows for proper growth and function of the horn, which can impact the bird's ability to feed and interact with its environment.

Although other attributes may be associated with different elements of a bird's anatomy or health, the condition and quality of the surface of the horn directly correlate with the bird's well-being and presentation in a showmanship context. A well-maintained horn enhances the bird's aesthetic appeal and can also be a sign of proper nutrition and care.
