the indian runner duck is a domestic breed of duck originating from east asia. unlike other ducks, the runner duck does not waddle; due to its upright posture, it runs, giving it its name. they also do not fly, and are found foraging on land more often than other ducks. runner duck hens are known to be good layers, but rarely build nests, instead laying eggs wherever they happen to be.

the crested duck is a domestic duck breed thought to have originated in the east indies. crested ducks appear similar at first to the common pekin duck breed, but have a distinctive crest on the head. they are typically seen in white, but can be seen in other colors, such as blue, wild-type and black (typically, only white and black are accepted in shows). the ‘crested’ gene can be lethal; if both parents show the gene, around 25% of offspring will be deformed and die, likely before hatching.
