Ah thats it mackstaa! The cockbird needs to be seagreen to produce what i described above. Knew it was something like that.
I have an opposite pair, hen normal and cock seagreen and I get seagreen hens and normal males that could be split to SG.
As to pied I always assume anything with the pied gene in it's breeding carries it or could manifest it during later moults or in breeding lines. I have not found any birds for sale here that DON't have the pied gene. All my original stock I bought as normals turned pied on me two years later!
