That's what the person I talked to said when I placed the order. I told her that I knew hatcheries sometimes included an extra, and often it was a cockerel. I told her I already had a rooster, and really, really didn't want a cockerel. She assured me that if there was an extra chick, it would be a pullet, since I ordered all pullets.My understanding is if you order all pullets the extra would also be from a sexed pullet bin of a same sized breed you ordered.
