Visual Sexing
This is to be used only as a quick guide and is not intended to replace DNA or surgical sexing. Most aviculturists are aware of the males being darker in color. This can only be based on the fact both birds originated in the same region of Africa or they are chicks from the same clutch. Also, hens may have a gradual dark-to-light transition of gray from the neck to the belly, while males have a more uniform gray in the same area.
