xs 2. I prefer 30%, and can usually maintain that completely dry if I am hatching in late spring/summer. Fall and winter I have to add a wet sponge to keep it right around 30% I am usually on track with my air cells, even at day 7, but I don't really worry too much about the size (unless it's extrememly small or big) until days 10-14.Where is your humidity at? If your air sac growth is slow then your humidity should be lowered. Some here at BYC incubate dry first 18 days. Personally I run 30-35% humidity those days then up to 70-75% for last few days. Found that at that humidity the air sac growth is right on track. With house humidity at 30% it takes a double shot glass of water set next to the egg turner to achieve 33% in incubator. Humidity is changed by changing the surface area of water in incubator. For hatching 70% RH it takes two coffee cups set in incubator for me.
And it begins!!! Thanks so much you guys!
Yay!! Congrats. Temps will affect when they hatch as well. If you have a slightly higher temp you can see action a day or two early. A slightly cooler temp for the incubation will delay it by a day or two. Hot and cool spots in the bator will also affect individual eggs and the chick's development.So my days may have been one off... I'm not sure now but...
