Sire: darkgreen opaline cock
Dame: lightgreen hen
There is one big surprise: violet. Another new factor is cinnamon.
Violet is a strange colour. There are three ways to get a visual violet:
In a green series bird, a violet factor resembles a dark factor. This means the lightgreen hen can't carry the violet factor. So the visual violet chick can't be a double factor violet. This only leaves the cobalt single factor violet where both the darkfactor and the violet factor come from the cock. So the 'darkgreen' cock must actually be a darkgreen with a violet factor.
A visual violet also means a blue series bird. So both parents must be split blue
Sire: darkgreen violet opaline cock/blue
Dame: lightgreen hen/blue
Since a opaline-cinnamon hen is born, a sex linked trait, the father must be split
Sire: darkgreen violet opaline cock/blue, cinnamon
Sire: darkgreen violet opaline cock/blue, cinnamon
Dame: lightgreen hen/blue
Expected offspring
The darkfactor and violet factor from the cock will result in offsping with both (25%), only darkfactor (25%), only violet factor (25%) and without both (25%).
25% of the offsping will be blue series:
Since for a visual violet you need a blue series bird with both the darkfactor and the violet factoer, the chances for a visual violet is 6.25% (= 25% x 25%)
The other factors (opaline and cinnamon):
