Hi, my geese are free range but I dont lock them up as we dont have foxes here. I would treat them like chooks to start with if they are to be locked up and just give them food in their hut at lock up time. I would not just keep them locked in a shed to start with though as they do need a lot of room, a pen around their shed would be ideal and then let them free range when they know the shed is theirs. We only feed ours mixed grain when the grass is frozen or there is a snow covering as they are real grazers . They do need plenty of water , easily accessible to swim and preen in, a pond is ideal . Folk do keep them with baths of water etc but to do geese right they need a pond as they do prefer to mate in water, mine go to sea to mate! Geese to me are a farm bird where streams , ponds etc are available to them, they are very intelligent and walk miles in a day , geese in a chook environment is not ideal as they get bored, territorial and therefor aggressive. I have around twenty five at the moment and they group as they want sometimes trios sometimes duos, mine go into their breeding groups( which are for life ) at breeding time but flock together when the yougsters are grown. Mine nest where they want but I do have a friend that provides boxes and they do use them but dont keep them around each other as a goose will leave its own nest to help take care of a brood that has hatched before hers! We dont fatten but kill when the grass dies in Autumn as this gives sweet good meet and still lean from life on the hill. I think thtas it for now, happy goose owning, they are addictive.
