What breed is my white feather legged chick?

[wc0838]

I recently bought some chicks and 2 of them were supposed to be white leghorns. As they have grown I have noticed some distinct differences and now wondering if this one isn't even a white leghorn after all. She is bigger than the other and has feathered legs. Could she still be a white leghorn or is she another breed? She is around 5-6 weeks old. Thanks for your help.

Looks like a white cochin to me, definitely not a buff brahma. (Wrong color and wrong comb).

And its a roo, too big of comb for 5-6 weeks.
