I am getting ready to set my incubator up again to hatch some Silkie eggs. I have 2 beautiful eggs from my Chinese girl. I was undecided on whether to stick them in the fridge or incubate them. I washed them with my chicken eggs. My questions are Will it hurt their chances of hatching after being washed and how long does it take to hatch a goose egg? I know chickens are 21 days.
