Why standard-colored Buff parents can produce different colors

The British Waterfowl Association describes an important feature of Buff Orpington breeding: the preferred exhibition color is associated with a heterozygous blue-dilution state. Standard-colored parents therefore do not produce only that same appearance. Lighter and darker offspring can arise without automatically proving a cross with another breed.

The page gives an expected distribution across many offspring, not a fixed result for each small hatch. A family with only a few ducklings need not match the theoretical proportions exactly. That difference introduces probability in inherited traits without requiring a complicated genetic lesson.

The intended buff body and the drake's differently colored head are also described separately. Sex and variety need clear captions. Conservation of the population and selection for an exhibition shade are related tasks, but rejecting every nonstandard-colored offspring without understanding its inheritance would miss part of the breeding biology.
