My mom was raised on a hatchery and has been answering some of my questions. One of the things I was confused about was that I have a hen/rooster in a pen, and sometimes the hen lays nice big eggs and sometimes smaller brown ones. My mom says those are pullet eggs. Just exactly what is that, and will it hatch? My mom is 80 with the start of Alzheimers so she can't remember if they hatched those pullet eggs.
