Aussie or Euro Yellow

[finchbreeder]

I understand other Gouldian mutations, but because there are several Yellows I get mixed up. SO if my YHPBYB cock goes to a YHPBGB hen and they produce 4 OHPBGB daughters - what is he?

FB, he's likely to be Euro yellow - unless the hen is split for Aus yellow he cannot produce yellow offspring if he is Aus yellow himself. If he produces dilute cocks - where the back green is more blue green than yellow green of the normal and the black ring around head goes blue instead of being black - then he's definitely Euro yellow. You did well to get all hens from them though .

There is no such thing as OH though, they will be YH.

Thanks. Yes I realised after posting that I had put OH instead of YH, cause frankly these guys are so rich in colouring on the head that it is orange. Only thing the hen might be split for is WB. She is a first timer and they had 2 rounds. 1st round 3 chicks fully feathered and ready to fledge, thunderstorm and they deserted the young. 2nd nest was the 4 and looking yesterday they are all girls so very happy.
