Please help rescue my duck eggs

[Paigey]

Hi, My duck has been sitting on her eggs for +- 28 days but she got off her eggs and went out the gate now we don't know where she is. I need some advice about the eggs please, and how to incubate them.

what breed?

Can you get ahold of an incubator? I am thinking in a pinch, if you have a styrofoam cooler you could place them in there with a dish of water and replace the lid with some sturdy half inch hardware cloth and set a heat lamp above that - you need a thermometer and a humidity indicator of some sort, ideally.

Any activity from the eggs? Sounds? Rocking?

I am not a hatcher, by the way. There is information in the Stickies on hatching https://www.backyardchickens.com/t/491013/goose-incubation-hatching-guide-completed
