Whistling-ducks generally do well, either in pens or in a park with access to extensive water area and good natural cover. They are gregarious outside the breeding season, and groups may bully smaller duck species, so should be kept in large areas, in which other birds have room to escape. Most need shelter in severe weather and a well-sheltered pen with frost-free night quarters for winter is suggested, or plenty of ground cover and/or straw to stand on, as they are susceptible to frostbite. They may be kept fully-flighted in aviaries, and have also been kept full-winged in open pens, tending not to wander. Perches should be provided at an appropriate height for pinioned or wing-clipped birds. Commercial pellets and grain are suitable for feeding.

Elevated nest boxes are appreciated by most species, although pinioned birds will use ground-level boxes; boxes may be placed over water or land. Eggs may be incubated by bantams and ducklings may be bantam-reared. Many species have been successfully parent-reared in captivity. Pairs kept isolated and fully flighted in a covered pen, with high-hung nest boxes "seldom fail to rear broods". Whistling-duck species may hybridise with one another and therefore should be kept in separate enclosures, and hybridisation has also occasionally been reported with Rosy-billed pochard (Netta peposaca).

The Lesser Whistling duck is probably the least hardy of the whistling-ducks. Rarely bred in captivity. Nest in close ground cover, ground-level nest box or perhaps raised nest box. Lay usually May to June.

May hybridise with Fulvous whistling-duck (Dendrocygna bicolor).


Het vrouwtje Lesser Whistling duck legt doorgaans zo'n 7-12 white eieren het broeden duurt 26-30 dagen.

Kunstmatig broeden:

De ideale relatieve luchtvochtigheid voor het uitbroeden van de meeste watervogeleieren is 55% voor grondbroeders en 40% bij holenbroeders. De temperatuur is meestal 37,4° C. Stel ventilatie in zoals aanbevolen door de fabrikant van de broedmachine. Eieren moeten minimaal 4 keer per dag automatisch of met de hand worden gedraaid. Naarmate de vrucht zich ontwikkelt, verliest het ei water en wordt de luchtzak groter. Bij normale ontwikkeling van een ei met een incubatietijd van 26-30 dagen neemt de luchtzak ongeveer een derde van het ei in beslag, dit bij drie dagen voor uitkomst. Reinheid is van vitaal belang en idealiter moet de luchtvochtigheid worden verhoogd tot 65% nadat de eerste tekenen van uitkomst zichtbaar worden.

Aanbevolen passende ringmaat voor de Lesser Whistling duck is 10 mm.
De gesloten pootring kan alleen aangebracht worden bij een jonge whistling duck van ongeveer 11-12 dagen oud.

It doesn't matter what leg that you band, but it's good to have a consistent system.
