they can be vicious, just wear full length trousers and don't be afraid to give them a nudge with your boot
for a while i used to go round to our mates road the corner when they were on holiday to feed and shut away/let out their chickens and geese and the chickens would go away them selves then one goose would go away with a bit of persuasion and maybe a little bedtime fight and then the other goose was totally blind in one eye and almost blind in the other, deaf, stubborn and vicious and required a good booting and a tennis racket and about half an hour to get her to go to bed!
Cheers Ed
