I have 5 chicks who are between 2-3 weeks old (I think) and wanna make sure they're all pullets. I can't keep any cockerels. I'm not even sure if their gender can be determined this young but I thought I'd show ya'll some pictures and see if anyone knows. The 2 yellows are orpingtons, the black one is supposedly a blue rock but if anyone thinks she's something else please lemme know, the grey one is a sapphire gem, and the one with the brown strip is an Easter Egger (I think).
