Did you get yours from Meyer?
I got 3 EEs from them, 3 weeks old yesterday. Two are patterned like the dark one in the first picture. One seems to be developing a black and gold coloring on the front and back of the neck, the other a black and orange coloring. The third was so white I wasn't sure they had put in 3 White Rocks and 2 EEs but her legs were slightly greenish and she did seem to have a bit of muff (but all the little fluffies including the Black Australorps do when they are a couple of days old). And she seemed to have a slightly brownish rather than yellowish head.
She seems to be developing an apricot coloring on her head, breast and back of the neck but no barring like your white one is showing.
And if you did get them from Meyer, did you order sexed chicks? I'm hoping not because that black one in the second picture sure looks like it is sprouting a cockerel comb.
