I know humidity plays an important role in incubating and hatching. Our house is really dry and I am having trouble getting my humidity above 38% most of the time it is about 33%. Will this cause problems? I know I read that to high a humidity wont let the air cell get big enough, but what will happen to the eggs if the humidity is to low? Should I be worried or is it ok? They are on day 12 and I have 28 out of 29 eggs that have good veining and movement, the air cells look good, bigger that when they started.
