What the chicks of a Ameraucana and a White Leghorn look like and lay, worked out from both breeds' standards.
A Ameraucana hen crossed with a White Leghorn rooster gives you what keepers call a first-generation (F1) cross. Every pullet should lay blue eggs (some may be green): both sides pass the blue gene. Most chicks (50%) get a pea comb. Expect a medium bird, a top layer, easygoing, the average of the two parents.
Preset to a Ameraucana hen and a White Leghorn rooster. Change either side to see how the blue gene and the brown coat move the shell colour.
He never lays, so his blue gene is read from his mother's eggs.
Probably Blue (possibly Green): 50–100% blue-based; otherwise White.
Brown shade shifts with a hen's age, diet and stress, so identical genes still lay a little differently. Speckling and bloom are cosmetic and not modelled.

Chicks land near the average of the two parents for these traits. Reaching one parent's extreme takes another generation of selection.
