So a green Egger hen has one blue and one brown gene. She can pass either to her offspring. So green x brown gives I think 25 percent green Eggers and the rest brown, if I'm picturing the squares correctly.
Updated Photo of my Light Brahma X Ameracauna/EE & Silver Leghorn crosses at exactly 12 weeks old.
Two of the light color pullets clearly have the A/EE puffy cheeks. And the dark one has the color/olive legs of an A/EE.
The one light one now has tan feathers on her back, so she has me a little stumped.
The other one appears to be clearly have a SL momma.
