Does a English White × Roux pairing breed true?

Yes. Every chick from this pairing carries the same color genes as the parents, so the pen breeds true.

English White × Roux: What Color Chicks Do You Get?

Every chick from this pairing is a Tuxedo-type Pharaoh.

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.

Tuxedo-type Pharaoh: A single dose of white spotting shows as partial white — bibs, belly patches, odd white primaries. How much white it puts on a bird varies a great deal, so expect a spread rather than a matched set.

What each parent brings

English White

Two doses of white spotting. White × white breeds white reliably; crossed to anything else it hands every chick a single dose, which is where tuxedo-patterned birds come from.

Built on recessive white spotting: two copies produce the mostly-white bird. Because the gene masks whatever color lies beneath, English White × colored crosses can throw surprises in later generations as hidden colors resurface. White × white breeds white reliably.

Roux Dilute

Simple recessive, homozygous. Two visibly roux parents breed 100% roux.

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.

What this assumes

Both parents are exactly what they are sold as. A bird carrying a hidden recessive — roux, celadon, white spotting — changes these numbers. Recessive carriers are invisible, which is the whole reason surprises happen.
These are per-chick probabilities, not a quota. A 50/50 split does not mean half your hatch of ten will be each. Small hatches swing hard; the ratios show up over dozens of chicks, not eight.
Coturnix inheritance is debated and varies by line. The modes used here are the ones consistently reported by breeders, and they match what our own variety guide says — but verify against your own stock before you plan a season around it.
Color only. Size, lay rate and temperament come from line selection, not from these genes.

Stop guessing which bird carries what

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.
