Celtic who lives in South Fl. is see mating among her geese so I'd say it will be soon for you too. I'm seeing the beginning of mating but no eggs yet.
Others who have experience with their geese sharing a nest will have to advise ya there, since my goose isn't laying yet. But i don't see why it would matter because they will all share in the duties of raising the goslings when they hatch. They do get mighty protective of their space when...
Have a bucket or broom with you and when he comes at you put one or the other between yo and him, I have used the broom alot to push my gander away. I will also make him back away as i walk towards him and I am 5'3" and weigh well... I'm not a big person. I won't hit my geese though.
I think thats why they are used as watch geese, their loudness and they can be mean. I can only go by what I've heard though since I have never met any Chinese in person. Would love to though.
You know you need to post some pics of your geese, We love to see pics. and I always know when my gander is mating, he announces it to the whole county.
My gander doesn't talk he hollers at all hours of the night, I never hear the goose only the gander. They have their own safe sleeping quarters so other than he just likes to hear himself scream there is no reason for it.
