Having all sorts of stock here geese,ducks,chickens,horses,sheep,dogs and cats i can put hand on heart and say they are the only ones who dont give me any trouble,mine are on a pond right infront of my front door behind stock fence,they will come running in the morning as soon as they see me come out of the door as they know thats when they get feed but they stop short of the fence,i have 12 in total they did used to free range but to be honest it was a bit of a pain as the dogs kept rolling in the poo,mine will easily follow me with a bucket of food and are very tame with me as i had them from a week old,however they are not so friendly with people they do not know,they are also quite happy to be rounded up by my collie pup,.
I do also have another little flock of geese in another area that are guard geese,i was sold 2 geese as a pair it turned out they were both ganders! so i bought 2 ladies to go with them,these geese are completely different from the ones on my pond they are guard geese and do there job brilliantly,they live next to my gate so i know the minute someone is on my property,however even i who feeds them ever day would NEVER go in there pen without protection as they would have me,1 of them gave me a very nasty bruise on my arm.
I have tried to give you both sides of keeping geese in that they are not all the same.
It would depend on if you wanted to buy youngish to grow them on or adult ones,not all adults are like my guard geese it all depends on how much they have been handled.
If i were you i would go for goslings or a well handled goose as the last thing you want even if they are for meat is to walk into your field and be attacked by a goose!
Mine only have a couple of scoops of mixed corn in the morning.
