I have 12 eggs in my incubator day 11. Mix of white,brown, green, and blue. I can see perfectly in the white eggs, even saw the chicks moving. 2 brown eggs I see no development in. But the rest of the brown, blue, and green I can't tell. They are definitely dark but I can't tell what I'm looking at. What do I do? Just let them be and see of they hatch? I never knew this would be so exciting. When I saw that little easter horn embryo move I nearly jumped out of my skin.
