He did, Miss Lydia, she was killed by a fox three weeks ago.
I'm new to the forum (though very relieved to have found it!) and I've posted a thread about him sitting on the eggs that his mate left.
I've only just started keeping geese - a work colleague needed a new home for her goose and we decided to get her a companion at the same time. I'd planned on having another female but unfortunately I discovered that it was true about geese being notoriously difficult to sex - we accidentally ended up with a very handsome and characterful young gander!
So he's sitting on the eggs she left (it's day 21!) but I have no idea if they are fertile or not - and I think I need to be prepared in case any do hatch! (I think I should probably start a new thread about parental gosling care rather than hijacking this one for my own topic). I've read a number of old threads but they seem focussed on hand-rearing, when what I need to know is what I should do to make a safe warm gosling nursery for them and Dad, if they hatch.
If they don't hatch, I will get him either a new mate or a pair of babies to nurture as soon as possible - poor boy, despite my fleecy white jumper and forays into his pool with him, he is very isolated and lonely - not good for him.
