What the chicks of a Golden Comet and a Olive Egger look like and lay, worked out from both breeds' standards.
A Golden Comet hen crossed with a Olive Egger rooster gives you what keepers call a first-generation (F1) cross. About 50–100% of the pullets should lay olive eggs (some may be green); the others lay brown. Most chicks (50%) get a pea comb. Expect a medium bird, a top layer, calm, the average of the two parents.
Preset to a Golden Comet hen and a Olive Egger 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 Olive (possibly Green): 50–100% blue-based; otherwise Brown.
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.
