Goose eggs as light as a feather, should I incubate it?

I have seb's that were sitting on 9 eggs, we are now down to 2 . Today I decided to candle them, one is alive(one was ready to explode and one wasn't fertile). So I finished planting my second garden, go back up to the barn and all the girls are in the yard . I look in their coop and there are the eggs not even covered up, I think because I touched them they aren't sitting on them...OR because I put goslings in the coop beside them, they are more fascinated with them than sitting on their eggs
Anyways I put the one that is alive in the bator but I dont know about this other one, it is as light as a feather and when I candled it there is no air sac on top. I am so scared it will explode...What should I do? I have to decide pretty quick...

SMell it! If it is about to explode, you will smell it. OR, put it in a bowl of warm water and if it floats, TOSS IT! Super light means it's about to go boom or about to hatch. Do you hear any noises? Hold it to your ear. If there are scratching sounds or you hear anything, it might be good.

Ok Uno but i am scared

If it is light do not incubate, you are just setting yourself up for stinkiness!

I went out there and she was back on the nest, poor girl is probably sitting on a stink bomb.
