Unfortunately I didn't think to mark them before putting them in my bator. I didn't scrub them...just rubbed dirt off with my finger. I know I have 2 for sure (will be 3 or 4 maybe by the end of today) that I didn't wash at all and were pretty clean anyways. I washed mine with just tap water(well water,so no chemicals) I will let you know if they still hatch. I hope they do. I want more EE chickens haha !...I only have 2 EE hens and would like to have more.Oh and when I wash them, I let them air dry.Oh I have another question... I have to turn them manually...how often should I do this? The directions that came with the bator says 2-3 times a day..and the man who I bought it from said every 12 hours. I have marked an " X " on one side and an " O " on the other side and turn them to the opposite side every time I turn.
