Hi there. A couple questions for you. I read that a day or two before the chicks break the membrane, the membrane draws down and anywhere from a day to three days after the membrane is broken, the chick pips and emerges. My question is, does this all begin around day 18 so that they emerge around day 21? Or does the process START around day 21? Will I see these changes when I do my final candling on day 18? And, I assume they naturally position themselves to break the membrane. Does having the airspace turned toward the bottom of the egg or toward the top at lock-down, matter? Lastly, does high humidity need to occur before they break the inner membrane or is it okay to wait till they pip? I ask because it was suggested to me to delay increasing humidity since the air spaces aren't very big. I'm having a hard time getting the humidity down in the incubator to encourage some evaporation because the weather has been so hot and humid lately. Today is day 16. ( I candled this morning and the air spaces are a tiny bit bigger than my pencil line from two days ago).
