What the chicks of a Buff Orpington and a Silkie look like and lay, worked out from both breeds' standards.
A Buff Orpington hen crossed with a Silkie rooster gives you what keepers call a first-generation (F1) cross. The pullets should lay brown eggs: there is no blue gene in this cross. Every chick gets a single comb. About 50% of the chicks carry the dark skin and bones (fibromelanosis) of the Silkie. Expect a medium bird, a fair layer, hand-tame, the average of the two parents.
Preset to a Buff Orpington hen and a Silkie 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.
Too uncertain to call: 0–100% blue-based (Olive if it is, otherwise Brown). Add lineage to narrow it.
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.
