They all had Dixie Rainbows for mothers, which I assume means they could be anything. I cannot be sure they had the same Mothers or not, Bert Sr was there Daddy. I had 3 rainbows for Mommies.
I knew the females controlled the sex, and about the WZ. I still find it funny they did not all turn out barred or white and orange. They are nice birds though huge bodies and big thighs! I a thigh man, I love big thighs!
Well in that case they all should have got a barring gene from mom . So a case of who is momma or a genetic mutation . I once got a crested chick from lavender Ameraucana .
