We're on day 11 now. We've candled all our 18 eggs (Auracana, Buff Orpington, Dekalb, Barred Rock and others). We've seen the little guys wiggling around in half of them and definitive air spaces and dark areas in the others. The only two eggs I do not clearly see development in are two of the green blue eggs. I see air spaces and a darkened area, but never any really dark area or movement that says "chick!" to me. Are they developing? I'm concerned about what I'm reading about opening the incubator. I only open it when I turn them by hand and add water at the same time. So that's 3 x's a day. The water wiggler stays at 99.5-98.5 by the time I'm done. I saw someone put anti-slip drawer liner on top of their hardware cloth, so I did that last night. Temp and humidity were fine this morning. On one egg it left a few little dots of "color" when I turned it. Should I not use this liner cloth until day 18 or something? And how do you keep your humidity up after day 18 if you are not opening your incubator once in a while?
