There are two varieties: a brown-feathered one, and one with white feathers, and an orangish-yellow beak and shanks.
Both have long necks, and hold themselves somewhat upright. Their legs are far back on their bodies.
The ducks are small, weighing only up to small ducks, up to 3 pounds (1.4 kg.)
The females will lay up to 230 bluish-shelled eggs a year.
The birds can start breeding when they are 4 months old.
History Notes
The white variety was developed at the Ilan Research Station (Duck Research Center), TLRI,ROC in Taiwan.
Language Notes
Tsaiya Duck means “vegetable duck.”
