Hi everyone, we are pretty new to hatching chicken eggs, but we are already running into a problem. Our easter Egger hens eggs will not hatch. Three times now, twice in an incubator and once under a broody hen. The chick's form, and after an eggtopsy, we have no idea of why this is happening. We have had chick's perfectly formed, blood absorbed and yolk absorbed, but it never pipped. This was under the broody hen. In the incubator, the chick's seem to make it to day 20ish. Some yolk absorbed, most blood, but again no popping at all. We have had approx a 80 percent hatch rate, and 95 percent if we remove her eggs from the equation. She's a year and a half old if that makes any difference.
