Hi, just asking a question, we are on day 8-9 of incubation, I candled the eggs this arvo and there are chicks moving in them, but he air sac is quite large, it is taking up at least a 1/4 of the egg, will this hurt the chicks, we are in a dry spell here, and I am having to add water regularly to the incubator and finding that humidity is sometimes dropping to around 30% and once to 25%, the tempreture has stayed constant at 37.5 to 37.7 degrees celcius, but sits at 37.6 most of the time, the kids turned it off accidently once while I was at work and I now have it taped into the power board, but the chicks are still kicking in the eggs. I am having to add water at least 2 times a day to keep the humidity up to 40%, will this harm the chicks? This is our 2nd hatching, the first one was the opposite but is was raining all the time then and the natural air humidity was higher, those chicks survived, have never seen the air sac this big before, but can see movement of the chicks and they seen quite vigorous.
