Hello I am new to this site. I have had 2 clutches of eggs set in my incubator. The first clutch was supposed to hatch last Wednesday, and started to hatch last Sunday. The second clutch is not supposed to hatch till Thursday, but there is already one that is pipped. The question that I have is why are they hatching so early? I have one hen that sets on the nest for about 3-4 hours before she lays. Could this be why? The humidity is all right, but it is a still air incubator, so the temp goes from 98 to 102 degrees. They are also 'pullet' eggs, meaning the first eggs that the hens have ever laid. HELP!!!
