Black Coturnix Quail Hatching Eggs

Black Coturnix Quail are a striking, rare colour mutation of the standard Japanese quail. There is a combination of four genes that make up this unique mutation, with birds displaying the darkest plumage exhibiting each of the four genes in homozygous form;

Extended Brown (Tibetan) 

Fawn (Golden Manchurian) 

Mryle 

Fee 

The best examples of Black will display a sleek black plumage, beak, legs and toes with no white patches around the face/chin. Due to the extended brown gene carrying random white leakage, some birds may display a small white bib, beard, or facial patch. 
Some black chicks may also have yellow markings around the head or chest area when they first hatch, to being replaced with black feathers as they feather up.
