Hello...in my opinion as I see it
1.Blue Opaline Male + yellow Dark-Eyed Clear Female = ?...Green normals and Opaline hens and males split Opaline all split blue and all split recessive pied....Best breeding to improve recessive pieds when breeding a male youngster back to a visual blue recessive pied hen...or could use an Opaline youngster to a visual blue Rec Pied male.
2.Female Reccesive pied + Male Dominant Pied = ?...no colour..Normals and Dom pied all split recessive pied....not advised.
3.yellow Dark-Eyed Clear Female + Male Dominant Pied =?...Green normals and Dom pieds all split Recessive pied. ...not advised..
**Dark eyed clears are a form of Rec Pied**
***Breeding Dom Pieds and Recessive Pieds together is not advisable as it tends to give poor marked Dom Pieds.If you are breeding for show adding rec pied traits to Dom pieds will diminish the size quality.*****
Hope this helps
