Ok, I went out to take pics, and decided to see if they would ALL do the "egg squat" for me, and they all did. That makes them all pullets then, right? I don't know what that was on the egg then.
mags2009, did you look at the link wordgirl posted? because both fertile and non fertile eggs have a mark, but they are slightly different, with the fertile one being more of a bullseye and the non fertile one being more of a just a white spot. The link shows good pics. It could be you have all girls and you just say the white spot.
