Notitie:

Bar-headed geese are hardy, totally winter-resistant and easy to manage. They are suitable for most collections and may be kept in mixed groups, but can be aggressive while breeding. A large area of well-sheltered water should be available, also grass for grazing. Additional feed of Lundi Regular floating Pellets should be provided, with plenty of green food always available - germinating wheat may be used in winter when grass is not available.

Bar-headed geese are fairly easy to breed. They prefer natural cover or a kennel-type or wigwam nest box and use nest sites on islands including wooden nest boxes on anchored floating platforms - may tolerate second pair on same platform if boxes back-to-back. They normally lay eggs in April to May, but the start of laying may be delayed after a long cold winter; they may also lay a second clutch. Goslings may be parent hatched and reared, although this may not result in a high survival rate. Bar-headed goslings are not difficult to rear, although survival is decreased in rain and cold.

Breeding:
Het vrouwtje Bar-headed goose legt doorgaans zo'n 4-8 white eieren het broeden duurt 27-30 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 27-30 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.


Ringdagen:
Aanbevolen passende ringmaat voor de Bar-headed goose is 16 mm.
De gesloten pootring kan alleen aangebracht worden bij een jonge goose van ongeveer 12-14 dagen oud.

It doesn't matter what leg that you band, but it's good to have a consistent system.
Suggested: Left leg = Female, Right leg = Male
