I think it is really too soon to tell. When you have several different breeds together, it can be confusing because different breeds develop differently, with different sized combs on males and females. You can have a male of one breed with a tiny comb compared to the female of another breed. It is fun to guess, but you really won't know for a while yet. Different breeds have different body types too. For the longest time I thought my Easter Egger was a rooster because of her body type and tall tail, but no, she's just very butch. ;-) If they were all the same breed you could kind of compare them to each other and check for differences. Anyway, good luck getting what you want! They sure are pretty chicks...
