What the chicks of a Delaware and a Polish look like and lay, worked out from both breeds' standards.
A Delaware hen crossed with a Polish rooster gives you what keepers call a first-generation (F1) cross. The pullets should lay cream/tinted eggs: there is no blue gene in this cross. Every chick gets a single comb. Expect a large bird, a good layer, calm, the average of the two parents.
Preset to a Delaware hen and a Polish 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.

| Skin color | Yellow | White | White 50% · Yellow 50%yellow depends on a hidden carrier, so it could be 0%; a hatch or a known genotype can confirm (uncertain) |

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