Every chick from this pairing is a Pharaoh (wild-type brown).
Every chick from this pairing carries one copy of roux and none of them show it. Bred back to each other, or to any other carrier, roux reappears in about a quarter of the next hatch — which is why red-eyed chicks seem to come from nowhere. Band them now or you will lose track of which birds carry it.
None of these chicks will lay blue eggs — but every single one carries the celadon gene and will pass it on. This is exactly how blue skips a generation and reappears.
| Chick looks like | Carries, but does not show | Egg shell (hens) | Share of hatch |
|---|---|---|---|
| Pharaoh (wild-type brown) | roux + celadon | Normal | 100% |
Celadon is an egg-shell trait, not a plumage variety. A celadon bird is modelled here as wild-type Pharaoh plumage carrying two copies of ce — if your celadon line is also colored, run the plumage cross separately.
The ce gene is recessive: a hen needs two copies to lay blue, and roosters carry it invisibly. Celadon × celadon breeds true for blue eggs. A celadon hen's daughters by a non-carrier male all carry one copy and lay normal eggs — which is how blue 'disappears' for a generation and returns.

Roux is a simple recessive on its own locus — a bird needs two copies to show it. Two visibly roux parents breed 100% roux. A roux bird bred to a non-carrier gives normal-looking chicks that ALL carry roux, and carrier × carrier throws about a quarter roux — which is why red-eyed chicks 'appear from nowhere' in coveys that quietly carry it.

Quail Keeper Max stores every bird's variety and celadon status, builds 4-generation pedigrees, and predicts the hatch from your actual pairings — so the invisible carriers in your covey stop being invisible.
