If the eggs are laid they are already fertilized. You can go on your porch as long as you pay no mind to them and stay far away from them.
There are many birds that do not have to sit on their eggs constantly. Robins only sit on the eggs occasionally.
They won't if they go cold, which will likely happen if she leaves the nest, unless the eggs are artificially incubated, instead of the mothers heat, the growing chicks inside will die. It appears mother ducks will leave the nest during the laying phase and as long as it doesn't get below freezing outside, the eggs will do fine!
