Generally speaking, the quality of the Black Lady Pigeon does not only depend on the single factor that the finer the feather color, the better, but also depends on the comprehensive evaluation of multiple factors. The bloodline of the Black Lady Pigeon has a great influence on the quality. If the pigeon's ancestors have good bloodlines, then it may also have good qualities. The feather color of the Black Lady Pigeon should be black with fine patterns. The more uniform the color, the better.
However, feather color is only one aspect of evaluating quality and cannot be completely relied on. Health status is one of the important factors in evaluating the quality of Black Lady pigeons. Healthy pigeons should be selected and pigeons that carry problems such as diseases and parasites should be avoided. Therefore, when evaluating the quality of Black and Fine Lady pigeons, multiple factors need to be considered comprehensively, rather than relying solely on a single criterion that the finer the feather color, the better.
