Sibling / Breeding Question

[boredcolliejane]

If you have a gander and a goose who were raised together as day-olds, will they breed? I have read that they won't as they consider one another siblings. Does anyone have any additional thoughts on this?

Will they breed? Yes. Will they consider themselves Siblings? No.

Well I raised my trio of geese from day olds together, and my gander and his ladies are just that, a guy and his girlfriends not siblings at all

So will all eggs be fertile? And how do you retrieve the eggs without getting attacked by the gander? Will he become more aggressive as he fully develops?
