Notitie:

Cape Barren geese are hardy and easy to manage, but strong, aggressive including to humans (very aggressive in the breeding season) and good diggers. They require a separate spacious enclosure with good grazing and secure fencing well-buried to prevent their digging out. They are mainly terrestrial. Wheat and other grain, pellets, green food, and wholemeal bread should supplement good grazing; lucern (alfalfa) pellets may also be used.

Cape Barren geese are fairly easily bred but variable - some pairs are prolific. In Australia May to August (winter) is the common breeding season for captive birds. In the Northern hemisphere they lay usually November to April (peak December to January), so they often nest in mid-winter. A kennel-type box is often used but they also lay in open or close ground cover. A shelter area such as a large kennel-type structure should be provided sufficient for winter nesting, frost-proof and draught-proof for winter-hatched goslings and this may be supplemented by some good natural vegetation cover.

Both parents will defend the nest and young; fresh lettuce and sprouting grain should be provided to goslings as part of their diet. Goslings must be removed once reared. These birds frequently re-lay if the first clutch is removed for artificial incubation. Some pairs are unreliable parents and removal of eggs and hand rearing may be prefered for such birds. Goslings should be encouraged to exercise, and too rapid growth avoided to reduce the risk of Angel Wing. Unlike their parents, goslings readily make use of a water area. Both artificial hatching and rearing and broodies may be used; care should be taken to avoid imprinting on humans - imprinted males are liable to become particularly aggressive adults.

N.B. handle these birds with care as they may bite, scratch with their nails and bash with their wings. "Kick boards" (wooden boards on handles) have been used successfully and safely to move these geese without needing to catch and carry them.

Breeding:
Het vrouwtje Cape Barren Goose legt doorgaans zo'n 3-6 creamy white and not shiny eieren het broeden duurt 28-31 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 28-31 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 Cape Barren Goose is 20 mm.
De gesloten pootring kan alleen aangebracht worden bij een jonge large goose van ongeveer 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
