What the chicks of a Dominique and a New Hampshire look like and lay, worked out from both breeds' standards.
A Dominique hen crossed with a New Hampshire 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. Most chicks (50%) get a rose comb. Barring is sex-linked in this direction: the cockerels hatch barred and the pullets do not, so the chicks can be sexed on hatch day. Expect a medium bird, a good layer, calm, the average of the two parents.
♂♀ Sex-linked cross: barring tells cockerels from pullets at hatch.
Preset to a Dominique hen and a New Hampshire 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.

Barring and silver are carried on the Z chromosome, so which parent is which changes the chicks.

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