If it is a sex linked gene, like Seagreen is, then all the "normal" birds I sold off are probably splits. But that is a guess. The only way to tell is to breed more, pair up young and see what comes out of it. Since I'm not too keen to start off a gene line of siblings, I will try first by out-crossing with unrelated seagreen & SG split males to broaden a gene pool before I try cross offspring.
All theory, now to see if any of the young that come out the nest A) survive B) have any markings to write home about! Have all my birds in breeding mode but only 3 pairs in the nest on eggs.
I bred plants for years and if I learnt one thing from it... crossings never deliver what you expect and hardly ever deliver what you want
