When I started cooking my auntie ( Who used to cook for country hotels and shearers gangs ) gave me a couple of tips for cooking galahs ; first skin & boil them for two hours in salted water, then dry with a cloth and add in with the chickens when preparing a roast and cook well done in a slow oven, you can rescue the choox and leave the "Game" birds swimming in the gravy. She reckons no-one ever picked it as the galahs soaked up all the flavour from the chickens and you mixed a bit of good chicken meat with a fair helping of galah also folks were not as fussy during the big depression and I suppose being healthy and hungry didn't hurt either.
Birds are birds but this sort of bird you don't pluck, you just skin and you only use the breast meat usually unless making soup, can't taste any worse than emu or wild duck
