A couple things about the Geese:
Our last 2 geese where one male & female, that is just how it worked out when we picked them out, they where very consistent show winners btw. I had no problems having a male.
We had a kiddie pool for them to splash about in (and the ducks we had too). The pool had to be cleaned regularly, but the dirty water from it did wonders in the garden. One advantage to the cheapy kiddie pool was it could be moved around the yard after being emptied to make fertilizing different areas easier. One of the hens help raise the baby goslings, you should have seen her freak the first day her adopted chicks went swimming in the kiddie pool... lol.
My climate is very nice, so our coop was not a proper coop but a heavily modified chain link dog run that was covered with a make shift roof and with some solid sides added, little add hock perches, and an additional big Igloo dog house for critters that wanted a hiddy hole, all the live stock at night slept together in the coop/dog run. So Geese, Ducks, Chickens, & Goats.... very hippy dippy, but it worked. The rabbits had individual hutches.
During the day the birds where allowed to free range within the confines of the back yard.
Feed for the Birds: Was a combination of scratch, laying feed, Wild Bird Seed, oyster shell, alfalfa, cooked rice and snails, slugs, bugs and lots and lots of figs (when in season). Veggie & Fruit table/prep scraps. Neighbors would bring by stale bread and feed the birds too, seemed to make some of our older neighbors really happy to feed the ducks and geese. All birds where fed together though.
The geese we kept where Pilgrim. We did have an African Grey 1st but we had raised him so tame that a neighbor's kid killed him
(those parents actively encouraged their children to harm animals) before my kids or I could reach the child (that had run into our backyard without permission... another thing their parents didn't seem to care about) and intervene (we all ran, screaming at him, but he just smiled, grabbed it by the neck and snapped it's neck)... so the Pilgrims we raised to be more feral... they therefore would bite & run away from strangers while alerting. The Grey had been raised like a house pet, hand fed, taken every where with humans in the yard and had even slept in the kids rooms in a cage when small, it was petted daily and as a result he did not know to run away from any humans, and thought all humans where his friends... we where aware of how big he would get and we had wanted him 100% tame for people safety. We purposefully raised the next 2 geese to be less friendly for their safety, there is no doubt in my mind however that if we had raised the Pilgrims the same as the African Grey they would have been 100% tame too.
Geese can not be bribed as my kids discovered in their teen years
, they will alert, will defend if threatened... but would loose to a good sized predator. It is their ability to alert that helps the other critters seek shelter.
We did have night mammal predator problems over the years, but the dogs stopped the night attacks.
I hopes this helps.
PS: the geese, ducks and RIR where used as 4-H projects and show birds but where all hatchery bred stock.
