I never saw "eyes or an eye" or maybe idk what it looks like. I candled last night and all have active movement. the night before I had to dispose of a quitter- blood ring. So we'll see next week as to what hatches. Good luck to you!
My first hatch is due on the 15th too! a week after I placed my eggs in the bator 2 of my hens decided it was time to go broody, so my 2nd hatch will be the week after! 10 eggs in the bator & 13 eggs under 2 silkies
